Hermann Kinkelin

Hermann Kinkelin (11 November 1832 – 1 January 1913) was a Swiss mathematician and politician.

Life
His family came from Lindau on Lake Constance. He studied at the Universities of Zurich, Lausanne, and Munich. In 1865 he became professor of mathematics at the University of Basel, where until his retirement in 1908, the full burden of teaching of mathematics was his responsibility. In 1867 he was naturalized in Basel. He was also a statistician, he founded the Swiss Statistical Society and the Statistical-economic society in Basel and led the 1870 and 1880 Federal census in Basel.

Kinkelin's works dealt with the gamma function, infinite series, and solid geometry of the axonometric. Kinkelin produced more than 60 publications in actuarial mathematics and statistics. He was a founder of the Basel "mortality and age checkout" (later "Patria, Swiss life insurance company Mutual") and the Swiss Statistical Society, of which he was a member during 1877–86.

Hermann Kinkelin died in Basel on 1 January 1913.
