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]
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 ...
Kirchhoff and Bunsen discovered caesium and rubidium in 1861. In 1866, Christomanos brought the spectroscope to Greece and used the instrument on the island of Santorini to research the volcanic eruption of the Santorini caldera in 1866. [4] [5] Christomanos continued to restructure the chemistry department at the University. He brought ...

Gustav Robert Kirchhoff (German: [ˈgʊs.taf ˈkɪʁçhɔf]; 12 March 1824 – 17 October 1887) was a German physicist, chemist and mathematican who contributed to the fundamental understanding of electrical circuits, spectroscopy and the emission of black-body radiation by heated objects.
September 3–5 – Karlsruhe Congress, the first international meeting of chemists. Marcellin Berthelot rediscovers and names acetylene.; Robert Bunsen and Gustav Kirchhoff, using their newly improved spectroscope, discover and name caesium in mineral water from Bad Dürkheim, Germany.
