Topgolf is a global sports entertainment community headquartered in Dallas, Texas United States with locations throughout the North America, Australia, UAE, the UK. Topgolf operates 53 venues in the United States, United Kingdom, Australia, employs 15,000 Associates and serves 15 million guests annually; the Topgolf games can be played by all ages and skill levels, the microchipped golf balls score themselves, providing players with instant feedback on each shot's accuracy and distance. Players aim for 11 giant dartboard-like targets on a 215-yard outfield; the farther the shot goes and the closer to the pin, the more points the player receives. Each Topgolf venue features climate-controlled hitting bays for year-round play, beverage, music and HDTVs on which various sports games are shown, such as football and golf. Topgolf offers golf lessons, tournaments and corporate and social events; the Topgolf technology was developed in Watford, England between 1996 and 2001 by twin brothers Steve and Dave Jolliffe.
The idea for Topgolf came when the two brothers were practicing their swings on a driving range and began thinking of different ways they could improve their experience. The Jolliffes formed a company called World Golf Systems and installed the technology in a driving range in Watford, England in 2001. WGS licensed the technology to a UK development company, Baydrive. Baydrive developed two additional UK sites; the original idea, for a casual golf and bar/dining experience came from Barry Cumbie, PhD, Mark Murray, MD, while attending college at Auburn University. The business, today known as TopGolf emerged from Golf Entertainment International, the US licensee; this company was established in London in 2006 to create a compelling customer experience and to bring the technology and the experience to the United States. GEI was formed by David Main and Eric Wilkinson. GEI transformed the early Topgolf experience to include food, drinks and new games. GEI developed its first sites in Alexandria, Dallas and Chicago, Illinois.
It acquired both World Golf Systems and the UK licensee. GEI changed its name at that point to name of the game: TopGolf. Today, Topgolf has the world's largest digital golf audience. Richard Grogan was the Company’s Chairman and Chief Executive from its formation until 2012. David Main spearheaded its US development. Eric Wilkinson was the Company’s finance director. Other investors joined the Company as it developed these first sites — among them was the Callaway Golf Company and the WestRiver Group; this allowed not only the US development but the consolidation of the varied operations as well. Thomas Dundon became a significant investor in 2011. By 2014, WestRiver Group was TopGolf’s lead investor. WestRiver was founded and is run by Erik Anderson, Erik Anderson is the Chairman of Topgolf. In 2016, TEG created three new divisions. Topgolf, the golf entertainment venues in the U. S. and U. K. Topgolf International, the division focused on Topgolf's international expansion, Topgolf Media, the division focused on enhancing the Topgolf experience through advanced digital media, strategic partnerships and sponsorships.
Additionally in 2016, Providence Equity Partners made a sizable minority investment in TEG. On June 23, 2016, it was announced that Village Roadshow Theme Parks would open a venue next door to its popular theme parks, Warner Bros. Movie World, Wet'n'Wild Gold Coast, Australian Outback Spectacular and Paradise Country in Oxenford, Queensland in Australia; this will be the first Topgolf venue outside the US and the UK. As the company expanded, Callaway Golf Company became an investor in 2006 and in 2011. In 2008, the company was incorporated as Topgolf International, Inc. In 2017, Topgolf created a new television series titled Who Will Rock You, where eight of the best unsigned bands across the country compete for $50,000 and a Topgolf tour. Depending on the venue, guests are charged per game; the U. K. locations and venues in Alexandria and Wood Dale are the only venues. Guests are required to have a membership. Information such as high scores are linked to this membership. Membership is a one-time $5 cost.
There are 53 Topgolf locations, 49 in the United States, three in the United Kingdom, one in Australia
Population density is a measurement of population per unit area or unit volume. It is applied to living organisms, most of the time to humans, it is a key geographical term. In simple terms population density refers to the number of people living in an area per kilometer square. Population density is population divided by total land water volume, as appropriate. Low densities may lead to further reduced fertility; this is called the Allee effect after the scientist. Examples of the causes in low population densities include: Increased problems with locating sexual mates Increased inbreeding For humans, population density is the number of people per unit of area quoted per square kilometer or square mile; this may be calculated for a county, country, another territory or the entire world. The world's population is around 7,500,000,000 and Earth's total area is 510,000,000 square kilometers. Therefore, the worldwide human population density is around 7,500,000,000 ÷ 510,000,000 = 14.7 per km2. If only the Earth's land area of 150,000,000 km2 is taken into account human population density is 50 per km2.
This includes all continental and island land area, including Antarctica. If Antarctica is excluded population density rises to over 55 people per km2. However, over half of the Earth's land mass consists of areas inhospitable to human habitation, such as deserts and high mountains, population tends to cluster around seaports and fresh-water sources. Thus, this number by itself does not give any helpful measurement of human population density. Several of the most densely populated territories in the world are city-states and dependencies; these territories have a small area and a high urbanization level, with an economically specialized city population drawing on rural resources outside the area, illustrating the difference between high population density and overpopulation The potential to maintain the agricultural aspects of deserts is limited as there is not enough precipitation to support a sustainable land. The population in these areas are low. Therefore, cities in the Middle East, such as Dubai, have been increasing in population and infrastructure growth at a fast pace.
Cities with high population densities are, by some, considered to be overpopulated, though this will depend on factors like quality of housing and infrastructure and access to resources. Most of the most densely populated cities are in Southeast Asia, though Cairo and Lagos in Africa fall into this category. City population and area are, however dependent on the definition of "urban area" used: densities are invariably higher for the central city area than when suburban settlements and the intervening rural areas are included, as in the areas of agglomeration or metropolitan area, the latter sometimes including neighboring cities. For instance, Milwaukee has a greater population density when just the inner city is measured, the surrounding suburbs excluded. In comparison, based on a world population of seven billion, the world's inhabitants, as a loose crowd taking up ten square feet per person, would occupy a space a little larger than Delaware's land area; the Gaza Strip has a population density of 5,046 pop/km.
Although arithmetic density is the most common way of measuring population density, several other methods have been developed to provide a more accurate measure of population density over a specific area. Arithmetic density: The total number of people / area of land Physiological density: The total population / area of arable land Agricultural density: The total rural population / area of arable land Residential density: The number of people living in an urban area / area of residential land Urban density: The number of people inhabiting an urban area / total area of urban land Ecological optimum: The density of population that can be supported by the natural resources Demography Human geography Idealized population Optimum population Population genetics Population health Population momentum Population pyramid Rural transport problem Small population size Distance sampling List of population concern organizations List of countries by population density List of cities by population density List of city districts by population density List of English districts by population density List of European cities proper by population density List of United States cities by population density List of islands by population density List of U.

Metra is a commuter railroad in the Chicago metropolitan area. The railroad operates 242 stations on 11 different rail lines, it is the fourth busiest commuter rail system in the United States by ridership and the largest and busiest commuter rail system outside the New York City metropolitan area. There were 83.4 million passenger rides in 2014, up 1.3% from the previous year. The estimated busiest day for Metra ridership occurred on November 4, 2016—the day of the Chicago Cubs 2016 World Series victory rally. Using Chicago's rail infrastructure, much of which dates to the 1850s, the Illinois General Assembly established the parent Regional Transportation Authority to consolidate all public transit operations in the Chicago area, including commuter rail; the RTA's creation was a result of the anticipated failure of commuter service operated and owned by various private railroad companies in the 1970s. In 1984, RTA formed a commuter rail division to focus on rail operations, which branded itself as Metra in 1985.
Freight rail companies still operate some Metra routes under contracted service agreements. Metra owns all rolling stock and is responsible for all stations along with the respective municipalities. Since its inception, Metra has directed more than $5 billion into the commuter rail system of the Chicago metropolitan area. Since its founding in the 19th century, Chicago has been a major Midwestern hub in the North American rail network, it has more trackage radiating in more directions than any other city in North America. Railroads set up their headquarters in the city and Chicago became a center for building freight cars, passenger cars and diesel locomotives. By the 1930s Chicago had the world's largest public transportation system, but commuter rail services started to decline. By the mid-1970s, the commuter lines faced an uncertain future; the Burlington Northern, Milwaukee Road and North Western and Illinois Central were losing money and were using passenger cars dating as far back as the 1920s.
To provide stability to the commuter rail system, the Illinois General Assembly formed the Regional Transportation Authority in 1974. Its purpose was to plan the Chicago region's public transportation. In the beginning the Regional Transportation Authority commuter train fleet consisted of second-hand equipment, until 1976 when the first order of new EMD F40PH locomotives arrived; that F40PH fleet is still in service today. The companies that had long provided commuter rail in the Chicago area continued to operate their lines under contract to the RTA. Less than a decade the Regional Transportation Authority was suffering from ongoing financial problems. Additionally, two rail providers, the Rock Island Line and the Milwaukee Road, went bankrupt, forcing the RTA to create the Northeast Illinois Regional Commuter Railroad Corporation to operate their lines directly in 1982. In 1983 the Illinois Legislature reorganized the agency; that reorganization left the Regional Transportation Authority in charge of day-to-day operations of all bus, heavy rail and commuter rail services throughout the Chicago metropolitan area.
It was responsible for directing fare and service levels, setting up budgets, finding sources for capital investment and planning. A new Commuter Rail Division was created to handle commuter rail operations; the board of the RTA Commuter Rail Division first met in 1984. In an effort to simplify the operation of commuter rail in the Chicago area, in July 1985 it adopted a unified brand for the entire system–Metra, or Metropolitan Rail; the newly reorganized Metra service helped to bring a single identity to the many infrastructure components serviced by the Regional Transportation Authority's commuter rail system. However, the system is still known as the Commuter Rail Division of the RTA. Today, Metra's operating arm, the Northeast Illinois Regional Commuter Railroad Corporation, operates seven Metra owned routes. Four other routes continue to be operated by Union BNSF under contract to Metra. Service throughout the network is provided under the Metra name. Metra owns all rolling stock, controls fares and staffing levels, is responsible for most of the stations.
However, the freight carriers who operate routes under contract use their own employees and control the right-of-way for those routes. In the late 20th and early 21st century Metra experienced record ridership and expanded its services. In 1996 Metra organized its first new line, the North Central Service, running from Union Station to Antioch. By 2006 it added new intermediate stops to that same route, extended the Union Pacific / West Line from Geneva to Elburn and extended SouthWest Service from Orland Park to Manhattan. In 2012 it boasted 95.8% average on-time performance. It posted its fourth highest volume in its history despite decreases in employment opportunities in downtown Chicago. Metra continued to improve passenger service. Over the past three decades, Metra has invested more than $5 billion into its infrastructure; that investment has been used to purchase new rolling stock, build new stations, renovate tracks, modernize signal systems and upgrade support facilities. In addition to core improvements on the Union Pacific Northwest and Union Pacific West routes, planning advanced on two new Metra routes, SouthEast Service and the Suburban Transit Access Route.
Metra has been marred by allegations and investigations of corruption. In April 2002, board member
DuPage County, Illinois
DuPage County is a county in the U. S. state of Illinois, one of the collar counties of the Chicago metropolitan area. As of the 2010 census, the population was 916,924, its county seat is Wheaton. DuPage County has become developed and suburbanized, although some pockets of farmland remain in the county's western and northern parts; the county has a high socioeconomic profile and residents of Hinsdale and Oak Brook include some of the wealthiest people in the Midwest. On the whole, the county enjoys above average median household income levels and low overall poverty levels when compared to the national average. In 2018 Niche ranked two DuPage municipalities amongst the top 20 best places to live in America. DuPage County was formed on February 1839 out of Cook County; the county took its name from the DuPage River, which was, in turn, named after a French fur trapper, DuPage. The first written history to address the name, the 1882 History of DuPage County, Illinois, by Rufus Blanchard, relates: The DuPage River had, from time immemorial, been a stream well known.
It took its name from a French trader who settled on this stream below the fork previous to 1800. Hon. H. W. Blodgett, of Waukegan, informs the writer that J. B. Beaubien had spoken to him of the old Frenchman, Du Page, whose station was on the bank of the river, down toward its mouth, stated that the river took its name from him; the county name must have the same origin. Col Gurden S. Hubbard, who came into the country in 1818, informs the writer that the name DuPage, as applied to the river was universally known, but the trader for whom it was named lived there before his time. Mr. Beaubien says; this was in reply to Mr. Blodgett’s inquiry of him concerning the matter; the first white settler in DuPage County was Bailey Hobson, with Lewis Stewart, built a house in 1831 for the Hobson family at a site about 2 miles south of present-day downtown Naperville. Hobson built a mill to serve surrounding farmers. Today, the Hobson house still stands on Hobson Road in Naperville, the location of the mill is commemorated with a millstone and monument in today’s Pioneer Park.
According to the U. S. Census Bureau, the county has a total area of 336 square miles, of which 327 square miles is land and 8.9 square miles is water. The DuPage River and the Salt Creek flow through DuPage County. According to the Forest Preserve District of DuPage County, the highest point in the county is located at the Mallard Lake Landfill, which at its highest point is 982 feet above mean sea level. In recent years, average temperatures in the county seat of Wheaton have ranged from a low of 14 °F in January to a high of 87 °F in July, although a record low of −26 °F was recorded in January 1985 and a record high of 105 °F was recorded in July 1995. Average monthly precipitation ranged from 1.56 inches in February to 4.60 inches in August. Counties that are adjacent to DuPage include: Cook County Will County Kendall County Kane County I-55 I-88 I-290 I-294 I-355 US 20 US 34 IL 19 IL 38 IL 53 IL 56 IL 59 IL 64 IL 83 IL 390 DuPage County's population's distribution by race and ethnicity in the 2010 census was as follows: DuPage County has become more diverse.
The population of foreign-born residents increased from about 71,300 in 1990 to 171,000 by 2009 estimates. There were 325,601 households, out of which 37.00% had children under the age of 18 living with them, 60.90% were married couples living together, 7.90% had a female householder with no husband present and 28.00% were non-families. 22.90% of all households were made up of individuals and 6.80% had someone living alone, 65 years of age or older. The average household size was 2.73 and the average family size was 3.27. In the county, the population was spread out with 26.70% under the age of 18, 8.20% from 18 to 24, 32.40% from 25 to 44, 22.80% from 45 to 64 and 9.80% who were 65 years of age or older. The median age was 35 years. For every 100 females, there were 97.20 males. For every 100 females, age 18 and over, there were 94.20 males. The median income for a household in the county was $98,441 and the median income for a family was $113,086. Males had a median income of $60,909 versus $41,346 for females.

Marriage called matrimony or wedlock, is a or ritually recognised union between spouses that establishes rights and obligations between those spouses, as well as between them and any resulting biological or adopted children and affinity. The definition of marriage varies around the world not only between cultures and between religions, but throughout the history of any given culture and religion, evolving to both expand and constrict in who and what is encompassed, but it is principally an institution in which interpersonal relationships sexual, are acknowledged or sanctioned. In some cultures, marriage is recommended or considered to be compulsory before pursuing any sexual activity; when defined broadly, marriage is considered a cultural universal. A marriage ceremony is known as a wedding. Individuals may marry for several reasons, including legal, libidinal, financial and religious purposes. Whom they marry may be influenced by gender determined rules of incest, prescriptive marriage rules, parental choice and individual desire.
In some areas of the world, arranged marriage, child marriage and sometimes forced marriage, may be practiced as a cultural tradition. Conversely, such practices may be outlawed and penalized in parts of the world out of concerns of the infringement of women's rights, or the infringement of children's rights, because of international law. Around the world in developed democracies, there has been a general trend towards ensuring equal rights within marriage for women and recognizing the marriages of interfaith and same-sex couples; these trends coincide with the broader human rights movement. Marriage can be recognized by a state, an organization, a religious authority, a tribal group, a local community, or peers, it is viewed as a contract. When a marriage is performed and carried out by a government institution in accordance with the marriage laws of the jurisdiction, without religious content, it is a civil marriage. Civil marriage recognizes and creates the rights and obligations intrinsic to matrimony before the state.
When a marriage is performed with religious content under the auspices of a religious institution it is a religious marriage. Religious marriage recognizes and creates the rights and obligations intrinsic to matrimony before that religion. Religious marriage is known variously as sacramental marriage in Catholicism, nikah in Islam, nissuin in Judaism, various other names in other faith traditions, each with their own constraints as to what constitutes, who can enter into, a valid religious marriage; some countries do not recognize locally performed religious marriage on its own, require a separate civil marriage for official purposes. Conversely, civil marriage does not exist in some countries governed by a religious legal system, such as Saudi Arabia, where marriages contracted abroad might not be recognized if they were contracted contrary to Saudi interpretations of Islamic religious law. In countries governed by a mixed secular-religious legal system, such as in Lebanon and Israel, locally performed civil marriage does not exist within the country, preventing interfaith and various other marriages contradicting religious laws from being entered into in the country, civil marriages performed abroad are recognized by the state if they conflict with religious laws.
The act of marriage creates normative or legal obligations between the individuals involved, any offspring they may produce or adopt. In terms of legal recognition, most sovereign states and other jurisdictions limit marriage to opposite-sex couples and a diminishing number of these permit polygyny, child marriages, forced marriages. In modern times, a growing number of countries developed democracies, have lifted bans on and have established legal recognition for the marriages of interfaith and same-sex couples; some cultures allow the dissolution of marriage through annulment. In some areas, child marriages and polygamy may occur in spite of national laws against the practice. Since the late twentieth century, major social changes in Western countries have led to changes in the demographics of marriage, with the age of first marriage increasing, fewer people marrying, more couples choosing to cohabit rather than marry. For example, the number of marriages in Europe decreased by 30% from 1975 to 2005.
In most cultures, married women had few rights of their own, being considered, along with the family's children, the property of the husband. In Europe, the United States, other places in the developed world, beginning in the late 19th century and lasting through the 21st century, marriage has undergone gradual legal changes, aimed at improving the rights of the wife; these changes included giving wives legal identities of their own, abolishing the right of husbands to physically discipline their wives, giving wives property rights, liberalizing divorce laws, providing wives with reproductive rights of their own, requiring a wife's consent when sexual relations occur. These changes have occurred in Western countries. In the 21st century, there continue to be controversies regarding the legal status of married women, legal acceptance of or leniency towards violence within marriage, traditional marriage customs such as dowry and bride price, for
A ZIP Code is a postal code used by the United States Postal Service in a system it introduced in 1963. The term ZIP is an acronym for Zone Improvement Plan; the basic format consists of five digits. An extended ZIP+4 code was introduced in 1983 which includes the five digits of the ZIP Code, followed by a hyphen and four additional digits that reference a more specific location; the term ZIP Code was registered as a servicemark by the U. S. Postal Service, but its registration has since expired; the early history and context of postal codes began with postal district/zone numbers. The United States Post Office Department implemented postal zones for numerous large cities in 1943. For example: The "16" was the number of the postal zone in the specific city. By the early 1960s, a more organized system was needed, non-mandatory five-digit ZIP Codes were introduced nationwide on July 1, 1963; the USPOD issued its Publication 59: Abbreviations for Use with ZIP Code on October 1, 1963, with the list of two-letter state abbreviations which are written with both letters capitalized.
An earlier list in June had proposed capitalized abbreviations ranging from two to five letters. According to Publication 59, the two-letter standard was "based on a maximum 23-position line, because this has been found to be the most universally acceptable line capacity basis for major addressing systems", which would be exceeded by a long city name combined with a multi-letter state abbreviation, such as "Sacramento, Calif." along with the ZIP Code. The abbreviations have remained unchanged, with the exception of Nebraska, changed from NB to NE in 1969 at the request of the Canadian postal administration, to avoid confusion with the Canadian province of New Brunswick. Robert Moon is considered the father of the ZIP Code; the post office only credits Moon with the first three digits of the ZIP Code, which describe the sectional center facility or "sec center." An SCF is a central mail processing facility with those three digits. The fourth and fifth digits, which give a more precise locale within the SCF, were proposed by Henry Bentley Hahn Sr.
The SCF sorts mail to all post offices with those first three digits in their ZIP Codes. The mail is sorted according to the final two digits of the ZIP Code and sent to the corresponding post offices in the early morning. Sectional centers do not deliver mail and are not open to the public, most of their employees work the night shift. Mail picked up at post offices is sent to their own SCF in the afternoon, where the mail is sorted overnight. In the case of large cities, the last two digits coincide with the older postal zone number thus: In 1967, these became mandatory for second- and third-class bulk mailers, the system was soon adopted generally; the United States Post Office used a cartoon character, which it called Mr. ZIP, to promote the use of the ZIP Code, he was depicted with a legend such as "USE ZIP CODE" in the selvage of panes of postage stamps or on the covers of booklet panes of stamps. In 1971 Elmira Star-Gazette reporter Dick Baumbach found out the White House was not using a ZIP Code on its envelopes.
Herb Klein, special assistant to President Nixon, responded by saying the next printing of envelopes would include the ZIP Code. In 1983, the U. S. Postal Service introduced an expanded ZIP Code system that it called ZIP+4 called "plus-four codes", "add-on codes", or "add-ons". A ZIP+4 Code uses the basic five-digit code plus four additional digits to identify a geographic segment within the five-digit delivery area, such as a city block, a group of apartments, an individual high-volume receiver of mail, a post office box, or any other unit that could use an extra identifier to aid in efficient mail sorting and delivery. However, initial attempts to promote universal use of the new format met with public resistance and today the plus-four code is not required. In general, mail is read by a multiline optical character reader that instantly determines the correct ZIP+4 Code from the address—along with the more specific delivery point—and sprays an Intelligent Mail barcode on the face of the mail piece that corresponds to 11 digits—nine for the ZIP+4 Code and two for the delivery point.
For Post Office Boxes, the general rule is. The add-on code is one of the following: the last four digits of the box number, zero plus the last three digits of the box number, or, if the box number consists of fewer than four digits, enough zeros are attached to the front of the box number to produce a four-digit number. However, there is no uniform rule, so the ZIP+4 Code must be looked up individually for each box; the ZIP Code is translated into an Intelligent Mail barcode, printed on the mailpiece to make it easier for automated machines to sort. A barcode can be printed by the sender, it is better to let the post office put one on. In general, the post office uses OCR technology, though in some cases a human might have to read and enter the address. Customers who send bulk mail can get a discount on postage if they have printed the barcode themselves and have presorted the mai
Chicago the City of Chicago, is the most populous city in Illinois, as well as the third most populous city in the United States. With an estimated population of 2,716,450, it is the most populous city in the Midwest. Chicago is the principal city of the Chicago metropolitan area referred to as Chicagoland, the county seat of Cook County, the second most populous county in the United States; the metropolitan area, at nearly 10 million people, is the third-largest in the United States, the fourth largest in North America and the third largest metropolitan area in the world by land area. Located on the shores of freshwater Lake Michigan, Chicago was incorporated as a city in 1837 near a portage between the Great Lakes and the Mississippi River watershed and grew in the mid-nineteenth century. After the Great Chicago Fire of 1871, which destroyed several square miles and left more than 100,000 homeless, the city made a concerted effort to rebuild; the construction boom accelerated population growth throughout the following decades, by 1900 Chicago was the fifth largest city in the world.
Chicago made noted contributions to urban planning and zoning standards, including new construction styles, the development of the City Beautiful Movement, the steel-framed skyscraper. Chicago is an international hub for finance, commerce, technology, telecommunications, transportation, it is the site of the creation of the first standardized futures contracts at the Chicago Board of Trade, which today is the largest and most diverse derivatives market gobally, generating 20% of all volume in commodities and financial futures. O'Hare International Airport is the one of the busiest airports in the world, the region has the largest number of U. S. highways and greatest amount of railroad freight. In 2012, Chicago was listed as an alpha global city by the Globalization and World Cities Research Network, it ranked seventh in the entire world in the 2017 Global Cities Index; the Chicago area has one of the highest gross domestic products in the world, generating $680 billion in 2017. In addition, the city has one of the world's most diversified and balanced economies, not being dependent on any one industry, with no single industry employing more than 14% of the workforce.
Chicago's 58 million domestic and international visitors in 2018, made it the second most visited city in the nation, behind New York City's approximate 65 million visitors. The city ranked first place in the 2018 Time Out City Life Index, a global quality of life survey of 15,000 people in 32 cities. Landmarks in the city include Millennium Park, Navy Pier, the Magnificent Mile, the Art Institute of Chicago, Museum Campus, the Willis Tower, Grant Park, the Museum of Science and Industry, Lincoln Park Zoo. Chicago's culture includes the visual arts, film, comedy and music jazz, soul, hip-hop and electronic dance music including house music. Of the area's many colleges and universities, the University of Chicago, Northwestern University, the University of Illinois at Chicago are classified as "highest research" doctoral universities. Chicago has professional sports teams in each of the major professional leagues, including two Major League Baseball teams; the name "Chicago" is derived from a French rendering of the indigenous Miami-Illinois word shikaakwa for a wild relative of the onion, known to botanists as Allium tricoccum and known more as ramps.
The first known reference to the site of the current city of Chicago as "Checagou" was by Robert de LaSalle around 1679 in a memoir. Henri Joutel, in his journal of 1688, noted that the eponymous wild "garlic" grew abundantly in the area. According to his diary of late September 1687:...when we arrived at the said place called "Chicagou" which, according to what we were able to learn of it, has taken this name because of the quantity of garlic which grows in the forests in this region. The city has had several nicknames throughout its history such as the Windy City, Chi-Town, Second City, the City of the Big Shoulders, which refers to the city's numerous skyscrapers and high-rises. In the mid-18th century, the area was inhabited by a Native American tribe known as the Potawatomi, who had taken the place of the Miami and Sauk and Fox peoples; the first known non-indigenous permanent settler in Chicago was Jean Baptiste Point du Sable. Du Sable arrived in the 1780s, he is known as the "Founder of Chicago".
In 1795, following the Northwest Indian War, an area, to be part of Chicago was turned over to the United States for a military post by native tribes in accordance with the Treaty of Greenville. In 1803, the United States Army built Fort Dearborn, destroyed in 1812 in the Battle of Fort Dearborn and rebuilt; the Ottawa and Potawatomi tribes had ceded additional land to the United States in the 1816 Treaty of St. Louis; the Potawatomi were forcibly removed from their land after the Treaty of Chicago in 1833. On August 12, 1833, the Town of Chicago was organized with a population of about 200. Within seven years it grew to more than 4,000 people.
