Robert Bunsen and Gustav Kirchhoff
Such studies opened the field of spectrum analysis, which became of great importance in the study of the Sun and stars and also led Bunsen almost immediately to his discovery of two alkali-group metals , cesium and rubidium. After taking a Ph. As professor at Heidelberg —99 , he built up an excellent school of chemistry. Never married, he lived for his students, with whom he was very popular, and his laboratory. He chiefly concerned himself with experimental and analytical work.
Robert Bunsen is most familiar today in association with the Bunsen burner , a device found in educational chemistry laboratories around the word. Ironically, Bunsen only made minor alterations to the familiar burner, rather than inventing it, and made many more generally important contributions to science. Indeed, in work he carried out with Gustav Kirchhoff, Bunsen helped lay the foundations of spectroscopy , a field that has had a tremendous impact on the modern understanding of the world. He spent several years following this achievement traveling through Western Europe. Upon his return, Bunsen taught at several different universities, including institutions in Marburg and Breslau, before settling at Heidelberg, where he taught from until his retirement, and established an exceptional chemistry department. There he was habitually absorbed by his experiments and analyses, never finding the time nor the inclination to marry.
He investigated emission spectra of heated elements, and discovered caesium in and rubidium in with the physicist Gustav Kirchhoff. Bunsen developed several gas-analytical methods, was a pioneer in photochemistry , and did early work in the field of organoarsenic chemistry. With his laboratory assistant, Peter Desaga , he developed the Bunsen burner , an improvement on the laboratory burners then in use. His discovery of the use of iron oxide hydrate as a precipitating agent is still today the most effective antidote against arsenic poisoning. This interdisciplinary research was carried on and published in conjunction with the physician Arnold Adolph Berthold.
Robert Wilhelm Eberhard Bunsen March 31, - August 16, was a German chemist who contributed to the development of spectroscopy as a powerful method of chemical analysis.

Bunsen’s Early Career
In Robert Bunsen and Gustav Kirchhoff discovered two alkali metals, cesium and rubidium, with the aid of the spectroscope they had invented the year before. These discoveries inaugurated a new era in the means used to find new elements. The first 50 elements discovered—beyond those known since ancient times—were either the products of chemical reactions or were released by electrolysis. From the search was on for trace elements detectable only with the help of specialized instruments like the spectroscope. Early in his career he did research in organic chemistry, which cost him the use of his right eye when an arsenic compound, cacodyl cyanide, exploded. Bunsen was called to the University of Heidelberg in , and he soon arranged for Kirchhoff to teach at Heidelberg as well. He also made a number of improvements in chemical batteries for use in isolating quantities of pure metals—including one known as the Bunsen battery.
Toggle navigation. He is best known for the development of the laboratory heater that bears his name. His study of the emission spectra of heated elements led to the discovery of caesium in and rubidium in His father, Christian Bunsen, was the chief librarian and professor of modern philosophy at the University of Gottingen. Robert Bunsen studied chemistry, mineralogy and mathematics at the University of Gottingen. During his travels he met Friedlieb Runge who had discovered aniline and isolated caffeine.
