Facts about the History of the Discovery of Cesium Element
Cesium was discovered by Fustov Kirchoff and Robert Bunsen in 1860 from mineral water found in Dürkheim, Germany. It was the first element discovered by spectrum analysis.
Robert Wilhelm Bunsen
Robert Wilhelm Bunsen (1811-1899) invented many lecture-room and laboratory appliances, most famously the Bunsen burner. He also invented the spectroscope and with it discovered rubidium and caesium; greatly perfected methods of electrolysis, inventing a new battery; made many investigations among metallic and organic substances.

What is Cesium - IUPAC and the Modern Standardised Periodic Table
The Standardised Periodic Table in use today was agreed by the International Union of Pure Applied Chemistry, IUPAC, in 1985 and now recognises more periods and elements than Dimitri Mendeleev knew in his day in his day but still all fitting into his concept of the "Periodic Table" in which Cesium is just one element that can be found.
