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.
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 ...
[1] [2] He also coined the term black body in 1860. [3] Several different sets of concepts are named "Kirchhoff's laws" after him, which include Kirchhoff's circuit laws, Kirchhoff's law of thermal radiation, and Kirchhoff's law of thermochemistry. The Bunsen–Kirchhoff Award for spectroscopy is named after Kirchhoff and his colleague, Robert ...
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.
In 1860, the unexpected appearance of sky-blue and dark red was observed in spectral emissions by Robert Bunsen and Gustav Kirchhoff, leading to the discovery of two alkali metals, caesium and rubidium (dark red). [4] [1] Today, this low-cost method is used in secondary education to teach students to detect metals in samples qualitatively. [2]

Robert Bunsen and Gustav Kirchhoff further develop the spectroscope, which they used to pioneer the identification of the chemical elements in Earth, and also in the Sun. [32] Around 1862 Father Angelo Secchi developed the heliospectrograph, enabling him to study both the Sun and the stars, and identifying them as things intrinsically of the ...
