Transistor radio
–
A transistor radio is a small portable radio receiver that uses transistor-based circuitry. Their pocket size sparked a change in music listening habits. Before the transistor was invented, radios used vacuum tubes, although portable vacuum tube radios were produced, they were typically bulky and heavy. In the early 50s, though, models with tubes using one volt for the filament circuit and 67 volts for the circuit were produced. Bell Laboratories demonstrated the first transistor on December 23,1947, the scientific team at Bell Laboratories responsible for the solid-state amplifier included William Shockley, Walter Houser Brattain, and John Bardeen. After obtaining patent protection, the company held a conference on June 30,1948. There are many claimants to the title of the first company to produce practical transistor radios, Texas Instruments had demonstrated all-transistor AM radios as early as May 25,1954, but their performance was well below that of equivalent vacuum tube models. A workable all-transistor radio was demonstrated in August 1953 at the Düsseldorf Radio Fair by the German firm Intermetall and it was built with four of Intermetalls hand-made transistors, based upon the 1948 invention of the Transistron-germanium point-contact transistor by Herbert Mataré and Heinrich Welker. However, as with the early Texas Instruments units only prototypes were ever built, were the first to offer a production model starting in October 1954. The use of transistors instead of vacuum tubes as the elements meant that the device was much smaller, required far less power to operate than a tube radio. Since the transistor base current, its input impedance is low in contrast to the high input impedance of the vacuum tubes. It also allowed operation, since there were no filaments to heat up. By comparison, the radio could fit in a pocket and weighed half a pound or less. The now-familiar 9-volt battery was introduced for powering transistor radios, most radios included earphone jacks and came with single earphones that provided only mediocre-quality sound reproduction. Previously, Texas Instruments was producing instrumentation for the oil industry and locating devices for the U. S. Navy, the two companies worked together on the TR-1, looking to grow revenues for their respective companies by breaking into this new product area. In May 1954, Texas Instruments had designed and built a prototype and was looking for a radio manufacturer to develop. None of the major radio makers including RCA, Philco, and Emerson were interested. The President of I. D. E. A. at the time, Ed Tudor, jumped at the opportunity to manufacture the TR-1, predicting sales of the transistor radios at 20 million radios in three years

Texas
–
Texas is the second largest state in the United States by both area and population. Other major cities include Austin, the second most populous state capital in the U. S. Texas is nicknamed the Lone Star State to signify its former status as an independent republic, and as a reminder of the states struggle for independence from Mexico. The Lone Star can be found on the Texan state flag, the origin of Texass name is from the word Tejas, which means friends in the Caddo language. Due to its size and geologic features such as the Balcones Fault, although Texas is popularly associated with the U. S. southwestern deserts, less than 10 percent of Texas land area is desert. Most of the centers are located in areas of former prairies, grasslands, forests. Traveling from east to west, one can observe terrain that ranges from coastal swamps and piney woods, to rolling plains and rugged hills, the term six flags over Texas refers to several nations that have ruled over the territory. Spain was the first European country to claim the area of Texas, Mexico controlled the territory until 1836 when Texas won its independence, becoming an independent Republic. In 1845, Texas joined the United States as the 28th state, the states annexation set off a chain of events that caused the Mexican–American War in 1846. A slave state before the American Civil War, Texas declared its secession from the U. S. in early 1861, after the Civil War and the restoration of its representation in the federal government, Texas entered a long period of economic stagnation. One Texan industry that thrived after the Civil War was cattle, due to its long history as a center of the industry, Texas is associated with the image of the cowboy. The states economic fortunes changed in the early 20th century, when oil discoveries initiated a boom in the state. With strong investments in universities, Texas developed a diversified economy, as of 2010 it shares the top of the list of the most Fortune 500 companies with California at 57. With a growing base of industry, the leads in many industries, including agriculture, petrochemicals, energy, computers and electronics, aerospace. Texas has led the nation in export revenue since 2002 and has the second-highest gross state product. The name Texas, based on the Caddo word tejas meaning friends or allies, was applied by the Spanish to the Caddo themselves, during Spanish colonial rule, the area was officially known as the Nuevo Reino de Filipinas, La Provincia de Texas. Texas is the second largest U. S. state, behind Alaska, though 10 percent larger than France and almost twice as large as Germany or Japan, it ranks only 27th worldwide amongst country subdivisions by size. If it were an independent country, Texas would be the 40th largest behind Chile, Texas is in the south central part of the United States of America. Three of its borders are defined by rivers, the Rio Grande forms a natural border with the Mexican states of Chihuahua, Coahuila, Nuevo León, and Tamaulipas to the south

Indianapolis, is the capital and largest city of the U. S. state of Indiana and the seat of Marion County. It is in the East North Central region of the Midwestern United States, with an estimated population of 853,173 in 2015, Indianapolis is the second most populous city in the Midwest, after Chicago, and 14th largest in the U. S. The city is the economic and cultural center of the Indianapolis metropolitan area, home to 2 million people and its combined statistical area ranks 26th, with 2.4 million inhabitants. Indianapolis covers 372 square miles, making it the 16th largest city by area in the U. S. The city grew beyond the Mile Square, as completion of the National Road and advent of the railroad solidified the position as a manufacturing. Indianapolis is within a single-day drive of 70 percent of the nations population, Indianapolis has developed niche markets in amateur sports and auto racing. The city is perhaps best known for hosting the worlds largest single-day sporting event. The city is notable as headquarters for the American Legion and home to a significant collection of monuments dedicated to veterans and war dead, the most in the U. S. outside of Washington, D. C. Since the 1970 city-county consolidation, known as Unigov, local government administration has operated under the direction of an elected 25-member city-county council, Indianapolis is considered a high sufficiency global city. In 1816, the year Indiana gained statehood, the U. S. Congress donated four sections of land to establish a permanent seat of state government. Two years later, under the Treaty of St. Marys and this tract of land, which was called the New Purchase, included the site selected for the new state capital in 1820. The availability of new lands for purchase in central Indiana attracted settlers. Although many of these first European and American setters were Protestants, few African Americans lived in central Indiana before 1840. The first European Americans to permanently settle in the area that became Indianapolis were either the McCormick or Pogue families, on January 11,1820, the Indiana General Assembly authorized a committee to select a site in central Indiana for the new state capital. The state legislature approved the site, adopting the name Indianapolis on January 6,1821, in April, Alexander Ralston and Elias Pym Fordham were appointed to survey and design a town plan for the new settlement. Indianapolis became a seat of county government on December 31,1821, a combined county and town government continued until 1832, when Indianapolis incorporated as a town. Indianapolis became an incorporated city effective March 30,1847, Samuel Henderson, the citys first mayor, led the new city government, which included a seven-member city council. In 1853, voters approved a new city charter provided for an elected mayor

Indiana /ɪndiˈænə/ is a U. S. state located in the midwestern and Great Lakes regions of North America. Indiana is the 38th largest by area and the 16th most populous of the 50 United States and its capital and largest city is Indianapolis. Indiana was admitted to the United States as the 19th U. S. state on December 11,1816, before becoming a territory, varying cultures of indigenous peoples and historic Native Americans inhabited Indiana for thousands of years. Indiana has an economy with a gross state product of $298 billion in 2012. Indiana has several areas with populations greater than 100,000. The states name means Land of the Indians, or simply Indian Land and it also stems from Indianas territorial history. On May 7,1800, the United States Congress passed legislation to divide the Northwest Territory into two areas and named the section the Indiana Territory. In 1816, when Congress passed an Enabling Act to begin the process of establishing statehood for Indiana, a resident of Indiana is officially known as a Hoosier. The first inhabitants in what is now Indiana were the Paleo-Indians, divided into small groups, the Paleo-Indians were nomads who hunted large game such as mastodons. They created stone tools made out of chert by chipping, knapping and flaking, the Archaic period, which began between 5000 and 4000 BC, covered the next phase of indigenous culture. The people developed new tools as well as techniques to cook food, such new tools included different types of spear points and knives, with various forms of notches. They made ground-stone tools such as axes, woodworking tools. During the latter part of the period, they built mounds and middens. The Archaic period ended at about 1500 BC, although some Archaic people lived until 700 BC, afterward, the Woodland period took place in Indiana, where various new cultural attributes appeared. During this period, the people created ceramics and pottery, an early Woodland period group named the Adena people had elegant burial rituals, featuring log tombs beneath earth mounds. In the middle portion of the Woodland period, the Hopewell people began developing long-range trade of goods, nearing the end of the stage, the people developed highly productive cultivation and adaptation of agriculture, growing such crops as corn and squash. The Woodland period ended around 1000 AD, the Mississippian culture emerged, lasting from 1000 until the 15th century, shortly before the arrival of Europeans. During this stage, the people created large urban settlements designed according to their cosmology, with mounds and plazas defining ceremonial

RCA
–
RCA Corporation, founded as the Radio Corporation of America, was an American electronics company in existence from 1919 to 1986. General Electric took over the company in late 1985 and split it up the following year, after World War I began in August 1914, radio traffic across the Atlantic Ocean increased dramatically after the western Allies cut the German transatlantic telegraph cables. In 1917 the government of the United States took charge of the owned by the major companies involved in radio manufacture in the United States to devote radio technology to the war effort. All production of equipment was allocated to the U. S. Army, U. S. Navy, U. S. Marine Corps. The War Department and the Navy Department sought to maintain a monopoly of all uses of radio technology. The wartime takeover of all radio systems ended late in 1918, the war ended in November of that year. The ending of the governments monopoly in radio communications did not prevent the War. On 8 April 1919, naval Admiral W. H. G. Bullard, the proposal presented by the government was that if GE created an American-owned radio company, then the Army and Navy would effect a monopoly of long-distance radio communications via this company. This marked the beginning of a series of negotiations through which GE would buy the American Marconi company, the Army and the Navy granted RCA the former American Marconi radio terminals that had been confiscated during the War. Admiral Bullard received a seat on the Board of Directors of RCA for his efforts in establishing RCA, the result was federally-created monopolies in radio for GE and the Westinghouse Corporation and in telephone systems for the American Telephone & Telegraph Company. The first chief officer of RCA was Owen D. Young. RCAs incorporation papers required that a majority of its stock be held by American citizens, as the years went on, RCA either took over, or produced for itself, a large number of patents, including that of the superheterodyne receiver invented by Edwin Armstrong. Over the years, RCA continued to operate international services, under its subsidiary RCA Communications, Inc. GE used RCA as its retail arm for radio sales from 1919, Westinghouse also marketed home radios through RCA until 1930. In 1929, RCA purchased the Victor Talking Machine Company, then the worlds largest manufacturer of phonographs and this included a majority ownership of the Victor Company of Japan. The new subsidiary then became RCA Victor, with Victor, RCA acquired New World rights to the Nipper His Masters Voice trademark. This trademark is used by the British music & entertainment company HMV. RCA began selling the first electronic turntable in 1930, in 1931, RCA Victor began selling 33⅓ rpm records

Philco
–
Philco, was a pioneer in battery, radio, and television production. In North America, it is the Philco brand owned by Philips, in other markets, it is the Philco International brand owned by Electrolux. In the early 1920s, Philco made storage batteries, socket power battery eliminator units, with the invention of the rectifier tube, which made it practical to power radios by electrical outlets, in 1928, Philco decided to get into the booming radio business. They followed other radio makers such as Atwater-Kent, Zenith Electronics, RCA, Freshman Masterpiece, FADA Radio, by 1930, they were selling more radios than any other maker, a position they held for more than 20 years. Philco built many iconic radios and television sets, including the classic cathedral-shaped wooden radio of the 1930s, philo Farnsworth, who invented cathode ray tube television, worked at Philco for some time. Philco was founded in 1892 as Helios Electric Company, from its inception until 1904, the company manufactured carbon-arc lamps. As this line of business slowly foundered over the last decade of the 19th century, as the Philadelphia Storage Battery Company, in 1906 it began making batteries for electric vehicles. They later supplied home charging batteries to the infant radio industry, the Philco brand name appeared in 1919. From 1920 to 1927, all radios were powered by batteries which were fairly expensive. A very successful August 1925 product, called the Socket Power Battery Eliminator, was a unit that allowed users to operate their battery-powered radios from standard light or wall sockets. By 1927 over a million of units had been sold. However, the invention of the tube rectifier made this technology obsolete. In 1926, Philco decided to begin making radios, the first Philco radios were introduced in mid 1928, and 96,000 were produced that year, making Philco radios 26th in the nation in production volume. Up to that time most radios were handmade and priced for relatively wealthy consumers, Atwater-Kent, the leading radio seller, coincidentally was also located in Philadelphia. The Philadelphia Storage Battery Company decided that prices of radios could be scaled for a market by incorporating assembly line techniques then only used by the automobile industry. By the 1929 model year, Philco was in place behind Atwater-Kent. In 1930 the company sold 600,000 radios, grossed $34 million, by 1934 they had captured 30% of the domestic radio market. Philco radios were notable for their economy of design without sacrificing quality or durability, like other makers of the era, they offered a wide line of radios beginning with five-tube sets all the way up to high-fidelity consoles with 20 tubes in 1937-38

Museum of Modern Art
–
The Museum of Modern Art is an art museum located in Midtown Manhattan in New York City, on 53rd Street between Fifth and Sixth Avenues. MoMA has been important in developing and collecting modernist art, and is identified as one of the largest and most influential museums of modern art in the world. The MoMA Library includes approximately 300,000 books and exhibition catalogs, over 1,000 periodical titles, the archives holds primary source material related to the history of modern and contemporary art. The idea for The Museum of Modern Art was developed in 1929 primarily by Abby Aldrich Rockefeller and they became known variously as the Ladies, the daring ladies and the adamantine ladies. They rented modest quarters for the new museum in the Heckscher Building at 730 Fifth Avenue in Manhattan, and it opened to the public on November 7,1929, nine days after the Wall Street Crash. Abby had invited A. Conger Goodyear, the president of the board of trustees of the Albright Art Gallery in Buffalo, New York. At the time, it was Americas premier museum devoted exclusively to art. One of Abbys early recruits for the staff was the noted Japanese-American photographer Soichi Sunami. Goodyear enlisted Paul J. Sachs and Frank Crowninshield to join him as founding trustees, Sachs, the associate director and curator of prints and drawings at the Fogg Museum at Harvard University, was referred to in those days as a collector of curators. Goodyear asked him to recommend a director and Sachs suggested Alfred H. Barr, under Barrs guidance, the museums holdings quickly expanded from an initial gift of eight prints and one drawing. Its first successful exhibition was in November 1929, displaying paintings by Van Gogh, Gauguin, Cézanne. Abbys husband was opposed to the museum and refused to release funds for the venture. Nevertheless, he donated the land for the current site of the museum, plus other gifts over time. During that time it initiated many more exhibitions of noted artists, the museum also gained international prominence with the hugely successful and now famous Picasso retrospective of 1939–40, held in conjunction with the Art Institute of Chicago. In its range of presented works, it represented a significant reinterpretation of Picasso for future art scholars, Boy Leading a Horse was briefly contested over ownership with the Solomon R. Guggenheim Museum. In 1941, MoMA hosted the exhibition, Indian Art of the United States. His brother, David Rockefeller, also joined the board of trustees in 1948. David subsequently employed the noted architect Philip Johnson to redesign the garden and name it in honor of his mother

Deutsches Museum
–
The museum was founded on 28 June 1903, at a meeting of the Association of German Engineers as an initiative of Oskar von Miller. Its official name is Deutsches Museum von Meisterwerken der Naturwissenschaft und Technik and it is the largest museum in Munich. The main site of the Deutsches Museum is an island in the Isar river. The island did not have any buildings before 1772 because it was regularly flooded prior to the building of the Sylvensteinspeicher, in 1772 the Isar barracks were built on the island and, after the flooding of 1899, the buildings were rebuilt with flood protection. In 1903 the city announced that they would donate the island for the newly built Deutsches Museum. The island formerly known as Kohleninsel was then renamed Museumsinsel, in addition to the main site on the Museumsinsel, the museum has two branches in and near Munich and one in Bonn. The Flugwerft Schleißheim branch is located some 18 kilometres north of Munichs city centre close to Schleißheim Palace and it is based on the premises of one of the first military airbases in Germany founded just before World War I. The Flugwerft Schleißheim displays various interesting airplanes for which there was insufficient room at the Museumsinsel site in downtown Munich, among the more prominent exhibits is a Horten flying wing glider built in the 1940s, restored from the few surviving parts. A collection of the German constructions of VTOL planes developed in the 1950s and 1960s is unique, a range of Vietnam era fighter planes as well as Russian planes taken over from East Germany after the reunification are on display. This outstation also features a dedicated to the restoration of all types of airplanes intended for static display. The latest branch of the Deutsches Museum, located at Theresienhöhe in Munich, the branch located in Bonn was opened in 1995 and focuses on German technology, science and research after 1945. In 1883 he joined AEG and founded an office in Munich. The Frankfurt electricity exhibition in 1891 and several power plants contributed to the reputation of Oskar von Miller, in the early years, the exhibition and the collection of the Deutsches Museum were strongly influenced personally by Oskar von Miller. A few months before the 1903 meeting of the Society of German Engineers, Oskar von Miller gathered a group who supported his desire to found a science. In a showing of support this group spontaneously donated 260,000 marks to the cause, in June 1903, Prince Ludwig agreed to act as patron of the museum and the city of Munich donated Coal Island as a site for the project. In addition, exhibits began to arrive from Munich, Germany, as no dedicated museum building existed, the exhibits were displayed in the National Museum. On 12 November 1906, the exhibits at the National Museum were ceremonially opened to the public. Oskar von Miller opened the new museum on his 70th birthday,2 May 1925, from the beginning, the museum displays are backed up by documents available in a public library and archives, which are open seven days a week to ensure access to the working public

Superheterodyne receiver
–
It was invented by US engineer Edwin Armstrong in 1918 during World War I. Virtually all modern radio receivers use the superheterodyne principle, Superheterodyne is a contraction of supersonic heterodyne, where supersonic indicates frequencies above the range of human hearing. The word heterodyne is derived from the Greek roots hetero- different, however, the signal from a continuous wave transmitter did not have any such inherent modulation and Morse Code from one of those would only be heard as a series of clicks or thumps. Fessendens idea was to run two Alexanderson alternators, one producing a carrier frequency 3 kHz higher than the other. In the receivers detector the two carriers would beat together to produce a 3 kHz tone thus in the headphones the Morse signals would then be heard as a series of 3 kHz beeps, for this he coined the term heterodyne meaning generated by a difference. The superheterodyne principle was devised in 1918 by U. S. Army Major Edwin Armstrong in France during World War I and he invented this receiver as a means of overcoming the deficiencies of early vacuum tube triodes used as high-frequency amplifiers in radio direction finding equipment. The strategic value was so high, however, that the British Admiralty felt the high cost was justified, Armstrong realized that if radio direction-finding receivers could be operated at a higher frequency, this would allow better detection of enemy shipping. However, at time, no practical short wave amplifier existed. Armstrong eventually deduced that this was caused by a supersonic heterodyne between the carrier frequency and the regenerative receivers oscillation frequency. Thus if a station was transmitting on 300 kHz and the receiver was set to 400 kHz, the station would be heard not only at the original 300 kHz. Armstrong realized that this was a solution to the short wave amplification problem, since the beat frequency still retained its original modulation. He termed this the intermediate frequency often abbreviated to IF, in December 1919, Major E. H. Armstrong gave publicity to an indirect method of obtaining short-wave amplification, called the super-heterodyne. Armstrong was able to put his ideas into practice, and the technique was adopted by the military. For early domestic radios, tuned radio frequency receivers were more popular because they were cheaper, easier for an owner to use. Armstrong eventually sold his patent to Westinghouse, who then sold it to RCA. Early superheterodyne receivers used IFs as low as 20 kHz, often based on the self-resonance of iron-cored transformers and this made them extremely susceptible to image frequency interference, but at the time, the main objective was sensitivity rather than selectivity. Using this technique, a number of triodes could be made to do the work that formerly required dozens of triodes. By the mid-1930s however, superheterodynes were using much higher frequencies, with tuned coils similar in construction to the aerial

Nashville, Tennessee
–
Nashville is the capital of the U. S. state of Tennessee and the county seat of Davidson County. It is located on the Cumberland River in the central part of the state. The city is a center for the music, healthcare, publishing, banking and transportation industries and it is known as a center of the country music industry, earning it the nickname Music City, U. S. A. Since 1963, Nashville has had a consolidated city-county government which includes six municipalities in a two-tier system. Nashville is governed by a mayor, vice-mayor, and 40-member Metropolitan Council, thirty-five of the members are elected from single-member districts, five are elected at-large. Reflecting the citys position in government, Nashville is home to the Tennessee Supreme Courts courthouse for Middle Tennessee. According to 2015 estimates from the U. S. Census Bureau, the balance population, which excludes semi-independent municipalities within Nashville, was 654,610. The 2015 population of the entire 13-county Nashville metropolitan area was 1,830,345, the 2015 population of the Nashville-Davidson–Murfreesboro–Columbia combined statistical area, a larger trade area, was 1,951,644. The town of Nashville was founded by James Robertson, John Donelson, and it was named for Francis Nash, the American Revolutionary War hero. Nashville quickly grew because of its location, accessibility as a port on the Cumberland River, a tributary of the Ohio River. By 1800, the city had 345 residents, including 136 African American slaves and 14 free blacks, in 1806, Nashville was incorporated as a city and became the county seat of Davidson County, Tennessee. In 1843, the city was named the permanent capital of the state of Tennessee, by 1860, when the first rumblings of secession began to be heard across the South, antebellum Nashville was a prosperous city. The citys significance as a port made it a desirable prize as a means of controlling important river. In February 1862, Nashville became the first state capital to fall to Union troops, the state was occupied by Union troops for the duration of the war. Within a few years after the Civil War, the Nashville chapter of the Ku Klux Klan was founded by Confederate veteran John W. Morton, meanwhile, the city had reclaimed its important shipping and trading position and developed a solid manufacturing base. The post–Civil War years of the late 19th century brought new prosperity to Nashville and these healthy economic times left the city with a legacy of grand classical-style buildings, which can still be seen around the downtown area. Circa 1950 the state approved a new city charter that provided for the election of city council members from single-member districts. This change was supported because at-large voting diluted the minority populations political power in the city and they could seldom gain a majority of the population to support a candidate of their choice

Erie, Pennsylvania
–
Erie /ˈɪəri/ is a city in and the county seat of Erie County, Pennsylvania, United States. Named for the lake and the Native American tribe that resided along its shore, Erie is the fourth-largest city in Pennsylvania. With a population of 101,786 at the 2010 census, the estimated population in 2016 had decreased to 100,055. The Erie metropolitan area, equivalent to all of Erie County, Erie is situated between Buffalo, Cleveland, and Pittsburgh. Eries manufacturing sector remains prominent in the economy, though health care, higher education, technology, service industries. Erie is known as the Flagship City because of its status as the port of Oliver Hazard Perrys flagship Niagara. The city has also called the Gem City because of the sparkling lake. Cultures of indigenous peoples occupied the shoreline and bluffs in this area for thousands of years, the historic Iroquoian-speaking Erie Nation occupied this area before being defeated by the five nations of the Iroquois Confederacy in the 17th century during the Beaver Wars. The Iroquois tribes had developed and five nations formed a league in the 1500s. The Erie area became controlled by the Seneca, keeper of the door of the Iroquois. The name of the fort refers to the peninsula that juts into Lake Erie, the French term presque-isle means peninsula. When the fort was abandoned by the French in 1760 during the French and Indian War, the British established a garrison at the fort at Presque Isle that same year, three years before the end of the French and Indian War.25 in Continental currency. The Iroquois released the land to Pennsylvania in January 1789 for payments of $2,000 from Pennsylvania, the Seneca Nation separately settled land claims against Pennsylvania in February 1791 for the sum of $800. The General Assembly of Pennsylvania commissioned the surveying of land near Presque Isle through an act passed on April 18,1795, initial settlement of the area began that year. Lt. Colonel Seth Reed and his moved to the Erie area from Geneva, New York, they were Yankees from Uxbridge. They became the first European-American settlers of Erie, settling at what became known as Presque Isle, president James Madison began the construction of a naval fleet during the War of 1812 to gain control of the Great Lakes from the British. Daniel Dobbins of Erie and Noah Brown of Boston were notable shipbuilders who led construction of four schooner−rigged gunboats, commodore Oliver Hazard Perry arrived from Rhode Island and led the squadron to success in the historic Battle of Lake Erie. Erie was an important shipbuilding, fishing, and railroad hub during the mid-19th century, the city was the site where three sets of track gauges met

Milwaukee
–
Milwaukee is the largest city in the state of Wisconsin and the fifth-largest city in the Midwestern United States. The county seat of Milwaukee County, it is on Lake Michigans western shore, Milwaukees estimated population in 2015 was 600,155. Milwaukee is the cultural and economic center of the Milwaukee–Racine–Waukesha Metropolitan Area with an estimated population of 2,046,692 as of 2015. Ranked by estimated 2014 population, Milwaukee is the 31st largest city in the United States, the first Europeans to pass through the area were French Catholic missionaries and fur traders. In 1818, the French Canadian explorer Solomon Juneau settled in the area, large numbers of German immigrants helped increase the citys population during the 1840s, with Poles and other immigrants arriving in the following decades. Known for its traditions, Milwaukee is currently experiencing its largest construction boom since the 1960s. In addition, many new skyscrapers, condos, lofts and apartments have been built in neighborhoods on and near the lakefront, the word Milwaukee may come from the Potawatomi language minwaking, or Ojibwe language ominowakiing, Gathering place. The first recorded inhabitants of the Milwaukee area are the Menominee, Fox, Mascouten, Sauk, Potawatomi, Ojibwe, many of these people had lived around Green Bay before migrating to the Milwaukee area around the time of European contact. In the second half of the 18th century, the Indians at Milwaukee played a role in all the wars on the American continent. During the French and Indian War, a group of Ojibwas, in the American Revolutionary War, the Indians around Milwaukee were some of the few Indians who remained loyal to the American cause throughout the Revolution. After American independence, the Indians fought the United States in the Northwest Indian War as part of the Council of Three Fires, during the War of 1812, Indians held a council in Milwaukee in June 1812, which resulted in their decision to attack Chicago. This resulted in the Battle of Fort Dearborn on August 15,1812, the War of 1812 did not end well for the Indians, and after the Black Hawk War in 1832, the Indians in Milwaukee signed their final treaty with the United States in Chicago in 1833. This paved the way for American settlement, Europeans had arrived in the Milwaukee area prior to the 1833 Treaty of Chicago. French missionaries and traders first passed through the area in the late 17th and 18th centuries, alexis Laframboise, in 1785, coming from Michilimackinac settled a trading post, therefore, he is the first European descent resident of the Milwaukee region. Early explorers called the Milwaukee River and surrounding lands various names, Melleorki, Milwacky, Mahn-a-waukie, Milwarck, for many years, printed records gave the name as Milwaukie. One story of Milwaukees name says, ne day during the thirties of the last century a newspaper calmly changed the name to Milwaukee, the spelling Milwaukie lives on in Milwaukie, Oregon, named after the Wisconsin city in 1847, before the current spelling was universally accepted. Milwaukee has three founding fathers, Solomon Juneau, Byron Kilbourn, and George H. Walker, Solomon Juneau was the first of the three to come to the area, in 1818. He was not the first European settler but founded a town called Juneaus Side, or Juneautown, in competition with Juneau, Byron Kilbourn established Kilbourntown west of the Milwaukee River and made sure the streets running toward the river did not join with those on the east side
