Career
The Hagenbach-Bischoff quota (a voting system) is named after him. He taught at the “Gewerbeschule” (vocational school) in Basel and was after his habilitation professor for mathematics at the University of Basel for one year. From 1863 to 1906 he was ordinary professor for physics in Basel (successor of Gustav Heinrich Wiedemann).
In 1874 he became director of the institute of physics at the newly founded “Bernoullianum” in Basel, and from 1874 to 1879 he was president of the Swiss Academy of Sciences.
Hagenbach-Bischoff was involved in the popularisation of science and at the “Bernoullianum” he gave more than 100 popular talks, such as one in 1896 on the newly discovered X rays.
