"Eduard Hagenbach-Bischoff (20 February 1833, in Basel – 23 December 1910, in Basel) was a Swiss physicist. The Hagenbach-Bischoff quota (a voting system) is named after him.
The son of the theologian Karl Rudolf Hagenbach, he studied physics and mathematics in Basel (with Rudolf Merian), Berlin (with Heinrich Wilhelm Dove and Heinrich Gustav Magnus), Geneva, Paris (with Jules Célestin Jamin) and obtained his Ph.D. in 1855 at Basel. He taught at the Gewerbeschule (vocational school) in Basel and was after his habilitation, a professor of mathematics at the University of Basel for one year." - (en.wikipedia.org 07.06.2021)
