Facts about the History of the Discovery of Cesium
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 (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

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
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.
