Holy Roman Empire
–
The Holy Roman Empire was a multi-ethnic complex of territories in central Europe that developed during the Early Middle Ages and continued until its dissolution in 1806. On 25 December 800, Pope Leo III crowned the Frankish king Charlemagne as Emperor, reviving the title in Western Europe, more than three centuries after the fall of the Western Roman Empire. The title was revived in 962 when Otto I was crowned emperor, fashioning himself as the successor of Charlemagne, some historians refer to the coronation of Charlemagne as the origin of the empire, while others prefer the coronation of Otto I as its beginning. Scholars generally concur, however, in relating an evolution of the institutions and principles constituting the empire, the office of Holy Roman Emperor was traditionally elective, although frequently controlled by dynasties. Emperor Francis II dissolved the empire on 6 August 1806, after the creation of the Confederation of the Rhine by Napoleon, before 1157, the realm was merely referred to as the Roman Empire. In a decree following the 1512 Diet of Cologne, the name was changed to Holy Roman Empire of the German Nation, by the end of the 18th century, the term Holy Roman Empire of the German Nation had fallen out of official use. As Roman power in Gaul declined during the 5th century, local Germanic tribes assumed control, by the middle of the 8th century, however, the Merovingians had been reduced to figureheads, and the Carolingians, led by Charles Martel, had become the de facto rulers. In 751, Martel’s son Pepin became King of the Franks, the Carolingians would maintain a close alliance with the Papacy. In 768 Pepin’s son Charlemagne became King of the Franks and began an expansion of the realm. He eventually incorporated the territories of present-day France, Germany, northern Italy, on Christmas Day of 800, Pope Leo III crowned Charlemagne emperor, restoring the title in the west for the first time in over three centuries. After the death of Charles the Fat in 888, however, the Carolingian Empire broke apart, according to Regino of Prüm, the parts of the realm spewed forth kinglets, and each part elected a kinglet from its own bowels. After the death of Charles the Fat, those crowned emperor by the pope controlled only territories in Italy, the last such emperor was Berengar I of Italy, who died in 924. Around 900, autonomous stem duchies reemerged in East Francia, on his deathbed, Conrad yielded the crown to his main rival, Henry the Fowler of Saxony, who was elected king at the Diet of Fritzlar in 919. Henry reached a truce with the raiding Magyars, and in 933 he won a first victory against them in the Battle of Riade, Henry died in 936, but his descendants, the Liudolfing dynasty, would continue to rule the Eastern kingdom for roughly a century. Upon Henry the Fowlers death, Otto, his son and designated successor, was elected King in Aachen in 936 and he overcame a series of revolts from an elder brother and from several dukes. After that, the managed to control the appointment of dukes. In 951, Otto came to the aid of Adelaide, the queen of Italy, defeating her enemies, marrying her. In 955, Otto won a victory over the Magyars in the Battle of Lechfeld

German Empire
–
The German Empire was the historical German nation state that existed from the unification of Germany in 1871 to the abdication of Kaiser Wilhelm II in 1918, when Germany became a federal republic. The German Empire consisted of 26 constituent territories, with most being ruled by royal families and this included four kingdoms, six grand duchies, five duchies, seven principalities, three free Hanseatic cities, and one imperial territory. Although Prussia became one of kingdoms in the new realm, it contained most of its population and territory. Its influence also helped define modern German culture, after 1850, the states of Germany had rapidly become industrialized, with particular strengths in coal, iron, chemicals, and railways. In 1871, it had a population of 41 million people, and by 1913, a heavily rural collection of states in 1815, now united Germany became predominantly urban. During its 47 years of existence, the German Empire operated as an industrial, technological, Germany became a great power, boasting a rapidly growing rail network, the worlds strongest army, and a fast-growing industrial base. In less than a decade, its navy became second only to Britains Royal Navy, after the removal of Chancellor Otto von Bismarck by Wilhelm II, the Empire embarked on a bellicose new course that ultimately led to World War I. When the great crisis of 1914 arrived, the German Empire had two allies, Italy and the Austro-Hungarian Empire, Italy, however, left the once the First World War started in August 1914. In the First World War, German plans to capture Paris quickly in autumn 1914 failed, the Allied naval blockade caused severe shortages of food. Germany was repeatedly forced to send troops to bolster Austria and Turkey on other fronts, however, Germany had great success on the Eastern Front, it occupied large Eastern territories following the Treaty of Brest-Litovsk. German declaration of unrestricted submarine warfare in early 1917 was designed to strangle the British, it failed, but the declaration—along with the Zimmermann Telegram—did bring the United States into the war. Meanwhile, German civilians and soldiers had become war-weary and radicalised by the Russian Revolution and this failed, and by October the armies were in retreat, Austria-Hungary and the Ottoman Empire had collapsed, Bulgaria had surrendered and the German people had lost faith in their political system. The Empire collapsed in the November 1918 Revolution as the Emperor and all the ruling monarchs abdicated, and a republic took over. The German Confederation had been created by an act of the Congress of Vienna on 8 June 1815 as a result of the Napoleonic Wars, German nationalism rapidly shifted from its liberal and democratic character in 1848, called Pan-Germanism, to Prussian prime minister Otto von Bismarcks pragmatic Realpolitik. He envisioned a conservative, Prussian-dominated Germany, the war resulted in the Confederation being partially replaced by a North German Confederation in 1867, comprising the 22 states north of the Main. The new constitution and the title Emperor came into effect on 1 January 1871, during the Siege of Paris on 18 January 1871, William accepted to be proclaimed Emperor in the Hall of Mirrors at the Palace of Versailles. The second German Constitution was adopted by the Reichstag on 14 April 1871 and proclaimed by the Emperor on 16 April, the political system remained the same. The empire had a parliament called the Reichstag, which was elected by universal male suffrage, however, the original constituencies drawn in 1871 were never redrawn to reflect the growth of urban areas

Copley Medal
–
The Copley Medal is a scientific award given by the Royal Society, London, for outstanding achievements in research in any branch of science. It alternates between the physical and the biological sciences, the medal was created following a donation of £100 to be used for carrying out experiments by Sir Godfrey Copley, for which the interest on the amount was used for several years. A second donation of £1666 13s, 4d. was made by Sir Joseph William Copley in 1881, and the interest from that amount is used to pay for the medal. The medal in its current format is made of silver gilt, since its inception, it has been awarded to many notable scientists, including 52 winners of the Nobel Prize,17 in Physics,21 in Physiology or Medicine, and 14 in Chemistry. John Theophilus Desaguliers has won the medal the most often, winning in 1734,1736 and 1741, in 1976, Dorothy Hodgkin became the first and as of 2015 the only female recipient

Kassel
–
Kassel is a city located on the Fulda River in northern Hesse, Germany. It is the seat of the Regierungsbezirk Kassel and the Kreis of the same name and has 200,507 inhabitants in December 2015. The former capital of the state of Hesse-Kassel has many palaces and parks, including the Bergpark Wilhelmshöhe, Kassel is also known for the documenta exhibitions of contemporary art. The citys name is derived from the ancient Castellum Cattorum, a castle of the Chatti, Kassel was first mentioned in 913 AD, as the place where two deeds were signed by King Conrad I. The place was called Chasella and was a fortification at a crossing the Fulda river. A deed from 1189 certifies that Cassel had city rights, in 1567, the Landgraviate of Hesse, until then centered in Marburg, was divided among four sons, with Hesse-Kassel becoming one of its successor states. Kassel was its capital and became a centre of Calvinist Protestantism in Germany, strong fortifications were built to protect the Protestant stronghold against Catholic enemies. Secret societies, such as Rosicrucianism flourished, with Christian Rosenkreutz’s work Fama Fraternitis first published in 1617, in 1685, Kassel became a refuge for 1,700 Huguenots who found shelter in the newly established borough of Oberneustadt. Landgrave Charles, who was responsible for this act, also ordered the construction of the Oktagon. In the early 19th century, the Brothers Grimm lived in Kassel and they collected and wrote most of their fairy tales there. At that time, around 1803, the Landgraviate was elevated to a Principality, shortly after, it was annexed by Napoleon and in 1807 it became the capital of the short-lived Kingdom of Westphalia under Napoleons brother Jérôme. The Electorate was restored in 1813, having sided with Austria in the Austro-Prussian War to gain supremacy in Germany, the principality was annexed by Prussia in 1866. The Prussian administration united Nassau, Frankfurt and Hesse-Kassel into the new Prussian province of Hesse-Nassau, Kassel ceased to be a princely residence, but soon developed into a major industrial centre, as well as a major railway junction. Henschel & Son, the largest railway locomotive manufacturer in Germany at the end of the century, was based in Kassel. In 1870, after the Battle of Sedan, Napoleon III was sent as a prisoner to the castle of Wilhelmshohe above the city, during World War I the German military headquarters were located in the castle of Wilhelmshohe. In the late 1930s Nazis destroyed Heinrich Hübschs Kassel Synagogue, the most severe bombing of Kassel in World War II destroyed 90% of the downtown area, some 10,000 people were killed, and 150,000 were made homeless. Most of the casualties were civilians or wounded soldiers recuperating in local hospitals, Karl Gerland replaced the regional Gauleiter, Karl Weinrich, soon after the raid. The Allied ground advance into Germany reached Kassel at the beginning of April 1945, post-war, most of the ancient buildings were not restored, and large parts of the city area were completely rebuilt in the style of the 1950s

Leopold Gmelin
–
Leopold Gmelin was a German chemist. Gmelin was professor at the University of Heidelberg among other things, he worked on the red prussiate, Gmelin was a son of the physician, botanist and chemist Johann Friedrich Gmelin and his wife Rosine Schott. Due to his family he came in contact with medicine. Leopold Gmelin returned to Tübingen and again heard the lectures of Ferdinand Gottlieb Gmelin, in February 1811 Gmelin clashed with the medical student Gutike, according to an insult he challenged him to a duel, without serious injuries. Because duels were forbidden among students the incident was kept a secret at first, on March 10 Gmelin fled and went to Joseph Franz von Jacquin at the University of Vienna. Focus of his research was the Black pigment of oxen and calves eyes, in 1812 he received his doctorate in Göttingen in absentia. Until 1813 Gmelin went on a study trip through Italy. After his return, he began to work as a Privatdozent at the Heidelberg University since the winter semester of 1813/14, on 26 September of the following year he was appointed associate professor in Heidelberg. In the fall of 1814, he went on another trip to Paris to study at the Sorbonne. Together with his cousin, Christian Gottlob Gmelin he made the acquaintance of René Just Haüy, Joseph Louis Gay-Lussac, Louis Jacques Thénard,1816 Gmelin married Louise in Heidelberg-Kirchheim, a daughter of the Kirchheimer pastor Johann Conrad Maurer, the lawyer Georg Ludwig von Maurer became his brother-in-law. Together they had three daughters and one son, including Auguste, the wife of the physician Theodor von Dusch. As the chemist Martin Heinrich Klaproth died in Berlin in 1817, however, he refused and became full Professor of Chemistry at the Heidelberg University. There, a cooperation with Friedrich Tiedemann evolved with time. The two published The digestion after tests in 1826 and established the basis of the physiological chemistry, in the field of digestive chemistry Gmelin later discovered more components of bile and introduced Gmelins test. When Friedrich Wöhler worked on complex cyanogen compounds in 1822, Gmelin assisted him, from 1833 to 1838 Gmelin owned a paper mill in the north of Heidelberg situated Schriesheim, he had taken it over in the hope of profit. However, the work in the mill showed to be time and money consuming. In 1817 the first volume of Gmelins Handbook of Chemistry was published, till 1843 it was grown in the fourth edition up to 9 volumes. In this edition Gmelin included the Atomtheory and devoted much space to the increasingly important organic chemistry

Chemist
–
A chemist is a scientist trained in the study of chemistry. Chemists study the composition of matter and its properties, chemists carefully describe the properties they study in terms of quantities, with detail on the level of molecules and their component atoms. Chemists carefully measure substance proportions, reaction rates, and other chemical properties, the word chemist is also used to address Pharmacists in Commonwealth English. Chemists may specialize in any number of subdisciplines of chemistry, materials scientists and metallurgists share much of the same education and skills with chemists. The roots of chemistry can be traced to the phenomenon of burning, fire was a mystical force that transformed one substance into another and thus was of primary interest to mankind. It was fire that led to the discovery of iron and glasses, after gold was discovered and became a precious metal, many people were interested to find a method that could convert other substances into gold. This led to the protoscience called alchemy, the word chemist is derived from the New Latin noun chimista, an abbreviation of alchimista. Alchemists discovered many chemical processes that led to the development of modern chemistry, Chemistry as we know it today, was invented by Antoine Lavoisier with his law of conservation of mass in 1783. The discoveries of the elements has a long history culminating in the creation of the periodic table by Dmitri Mendeleev. The Nobel Prize in Chemistry created in 1901 gives an excellent overview of chemical discovery since the start of the 20th century. Jobs for chemists usually require at least a degree, but many positions, especially those in research. At the Masters level and higher, students tend to specialize in a particular field, postdoctoral experience may be required for certain positions. Workers whose work involves chemistry, but not at a complexity requiring an education with a degree, are commonly referred to as chemical technicians. Such technicians commonly do such work as simpler, routine analyses for quality control or in clinical laboratories, there are also degrees specific to become a Chemical Technologist, which are somewhat distinct from those required when a student is interested in becoming a professional Chemist. A Chemical technologist is more involved in the management and operation of the equipment and they are part of the team of a chemical laboratory in which the quality of the raw material, intermediate products and finished products is analyzed. They also perform functions in the areas of quality control. The higher the level achieved in the field of Chemistry, the higher the responsibility given to that chemist. Chemistry, as a field, have so many applications that different tasks/objectives can be given to workers/scientists with these different levels of education and/or experience

Chemical element
–
A chemical element or element is a species of atoms having the same number of protons in their atomic nuclei. There are 118 elements that have identified, of which the first 94 occur naturally on Earth with the remaining 24 being synthetic elements. There are 80 elements that have at least one stable isotope and 38 that have exclusively radioactive isotopes, iron is the most abundant element making up Earth, while oxygen is the most common element in the Earths crust. Chemical elements constitute all of the matter of the universe. The two lightest elements, hydrogen and helium, were formed in the Big Bang and are the most common elements in the universe. The next three elements were formed mostly by cosmic ray spallation, and are rarer than those that follow. Formation of elements with from 6 to 26 protons occurred and continues to occur in main sequence stars via stellar nucleosynthesis, the high abundance of oxygen, silicon, and iron on Earth reflects their common production in such stars. The term element is used for atoms with a number of protons as well as for a pure chemical substance consisting of a single element. A single element can form multiple substances differing in their structure, when different elements are chemically combined, with the atoms held together by chemical bonds, they form chemical compounds. Only a minority of elements are found uncombined as relatively pure minerals, among the more common of such native elements are copper, silver, gold, carbon, and sulfur. All but a few of the most inert elements, such as gases and noble metals, are usually found on Earth in chemically combined form. While about 32 of the elements occur on Earth in native uncombined forms. For example, atmospheric air is primarily a mixture of nitrogen, oxygen, and argon, the history of the discovery and use of the elements began with primitive human societies that found native elements like carbon, sulfur, copper and gold. Later civilizations extracted elemental copper, tin, lead and iron from their ores by smelting, using charcoal, alchemists and chemists subsequently identified many more, almost all of the naturally occurring elements were known by 1900. Save for unstable radioactive elements with short half-lives, all of the elements are available industrially, almost all other elements found in nature were made by various natural methods of nucleosynthesis. On Earth, small amounts of new atoms are produced in nucleogenic reactions, or in cosmogenic processes. Of the 94 naturally occurring elements, those with atomic numbers 1 through 82 each have at least one stable isotope, Isotopes considered stable are those for which no radioactive decay has yet been observed. Elements with atomic numbers 83 through 94 are unstable to the point that radioactive decay of all isotopes can be detected, the very heaviest elements undergo radioactive decay with half-lives so short that they are not found in nature and must be synthesized

Hanau
–
Hanau is a town in the Main-Kinzig-Kreis, in Hesse, Germany. It is located 25 km east of Frankfurt am Main and its station is a major railway junction and it has a port on the river Main, making it an important transport centre. Hanau is known for being the birthplace of Jakob and Wilhelm Grimm, since the 16th century it was a centre of precious metal working with many goldsmiths. It is home to Heraeus, one of the largest family-owned companies in Germany, in 1963, the town hosted the third Hessentag state festival. Until 2005, Hanau was the centre of the Main-Kinzig-Kreis. The historic core of Hanau is situated within a semicircle of the river Kinzig which flows into the river Main just west of the town, after this change, Hanau for the first time also extended to the south bank of the Main river. The name is derived of Hagenowe which is an out of Haag. As a place of settlement Hanau was first mentioned in 1143, then it was the site of a castle which used the waters of the river Kinzig as a defense. The castle belonged to a family, calling themselves of Hanau since the 13th century. Starting from this castle a village developed and became a town in 1303, as a result of this history, the main church of Hanau stood outside its walls in the village of Kinzdorf. The villagers moved into the town, Kinzdorf became a village leaving only the church. Only in the 15th century was the status of the Hanau parish church transferred to the church of Mary Magdalene within the town walls, shortly after the first town walls were built at the beginning of the 14th century, the town outgrew this limit. These new fortifications enclosed three elements, The medieval castle, the town of Hanau and the Vorstadt. At the end of the 16th century, Count Philipp Ludwig II attracted Protestant refugees from the Netherlands and this was of high economic interest for him because these Walloons brought high-class trade, their knowledge of jewellery and other production of luxury items and therefore taxes to his county. Out of this tradition, goldsmiths are still trained in Hanau, Hanau also was the site of the first workshop to produce Faience within Germany. These new citizens were granted privileges and they formed their own community, church and it took more than 200 years to amalgamate both. The new town – larger than the old one – was protected by a very modern fortification in Baroque-style which proved a big asset only a few years later in the Thirty Years War. The town survived a siege in 1637 with only minor damage, in 1736 Johann Reinhard III of Hanau-Lichtenberg, the last of the Counts of Hanau, died
