Robert Wilhelm Eberhard Bunsen (German:; 30 March 1811 [a] – 16 August 1899) was a German chemist. He investigated emission spectra of heated elements, and discovered caesium (in 1860) and rubidium (in 1861) with the physicist Gustav Kirchhoff. [11] The Bunsen–Kirchhoff Award for spectroscopy is named after Bunsen and Kirchhoff.
Spectroscope of Kirchhoff and Bunsen. The systematic attribution of spectra to chemical elements began in the 1860s with the work of German physicists Robert Bunsen and Gustav Kirchhoff, [30] who found that Fraunhofer lines correspond to emission spectral lines observed in laboratory light sources. This laid way for spectrochemical analysis in ...
Bunsen was recruiting countless scientists to assist in his academic research. Christomanos was involved with Bunsen and his associates. He also worked at different chemical institutions. Around this period, Kirchhoff and Bunsen invented the spectroscope. Kirchhoff used the instrument to pioneer the identification of the elements in the Sun.
The couple had five children. Clara died in 1869. He married Luise Brömmel in 1872. [6] Kirchhoff (left) and Robert Bunsen, c. 1850. Kirchhoff formulated his circuit laws, which are now ubiquitous in electrical engineering, in 1845, while he was still a student. He completed this study as a seminar exercise; it later became his doctoral ...

Kirchhoff, Bunsen, and Roscoe (1862) Roscoe and Arthur Schuster. Henry Enfield Roscoe was born in London, the son of Henry Roscoe (1800–1836) and Maria Roscoe, née Fletcher (1798–1885), and grandson of William Roscoe (1753–1831). [1] Stanley Jevons the Australian economist was a cousin.
