A German chemist by trade, Robert Bunsen investigated the emission spectra of heated elements.

Along with his partner Gustav Kirchhoff, he discovered rubidium and caesium.

He developed the Bunsen burner, which produces a near-colourless flame.

He also invented the hydro jet filter pump and a chemical battery called the Bunsen battery.

In 1860, he was blinded in one eye while conducting a chemistry experiment that led to his discovery of Rubidium and Cesium.

He was also invited to Iceland, where he made a significant contribution to geochemistry.

He bravely stood on the side of a geyser and lowered his scientific apparatus into its depths.

Bunsen also discovered a technique called spectrum analysis.

This technique was important for astronomy, since it allowed scientists to determine the elements in the stars.

After his doctorate, he taught at various universities and founded a renowned chemistry school in Heidelberg.

Bunsen was an important figure in the development of the field of spectroscopy.

Together with Kirchhoff, he developed a method to analyze the absorption and emission spectra of heated materials.
