Kirchhoff, Gustav Robert (1824-1887), a German physicist. Investigations in spectrum analysis enabled Kirchhoff and Robert Wilhelm Bunsen to discover the elements cesium (1860) and rubidium (1861). Kirchhoff formulated laws concerning heat radiation and electrical circuits. He was born in the East Prussian city of Königsberg (now Kaliningrad, Russia) and studied at the university there. Kirchhoff taught physics at the universities of Breslau, Heidelberg, and Berlin.
He built President Eisenhower an indoor golf-training machine, analyzed the Zapruder film and searched for an Egyptian pyramid's treasure chamber using cosmic rays. Aren't you dying to meet this wide-ranging scientist?
The man who had some theories about relativity was also an eccentric who gleefully eschewed socks, dodged German military service and spurned social conventions.
