Robert Bunsen's birthday marked with Google Doodle
Robert Bunsen, the German scientist who developed the Bunsen burner, has been honoured on what would have been his 200th birthday with a Google Doodle.
It shows a flame changing colour from blue to purple as a multicoloured chemicals bubble in a series of pots and test tubes while steam flies out of a coffee pot.
Born in Gottingen, Germany, on March 31 1811, Robert Wilhelm Eberhard Bunsen was a prominent chemist in his day who discovered the elements caesium and rubidium and developed the Bunsen cell battery.
But he is best remembered for the distinctive gas burner he developed with his laboratory assistant Peter Desaga in 1854 and 1855 to study the colour spectrum of different heated elements.
It was during the construction of new lab facilities at Heidelberg University that he came up with the idea.
