The details (from wikipedia)


Hans Friedrich Geitel (16 July 1855 in Braunschweig – 15 August 1923 in Wolfenbüttel) was a German physicist.


Through the relocation of his family, his father was a forester, Hans Geitel came to Blankenburg in 1861 and grew up in close proximity to Julius Elster. He attended school and high school together with Elster. A lifelong friendship developed between the two of them, their interest in science became a shared field of activity.

During their studies both spent two years in Heidelberg and Berlin. In 1879 Geitel got his teaching degree in Braunschweig and accepted a position as teacher at the Great School of Wolfenbüttel. In 1881 Geitel succeeded in getting Julius Elster to the school as well. There they intensified their joint researches. Karl Bergwitz (1875–1958), who continued their research, was one of their students there. In 1892 Geitel was elected a member of the German Academy of Sciences Leopoldina.


Geitel and Elster published works on meteorology, nuclear physics, and the photoelectric effects. Geitel recognized the law of radioactive decay in 1899 and coined the term atomic energy. In 1893 he invented the photocell.
