Hermann Senftleben (April 8, 1890, in Bremen – 1975 in Recklinghausen) was a German physicist and physical chemist.
He was then an assistant in Breslau (with Carl Hintze, Arnold Eucken and Otto Lummer) and Marburg (with Clemens Schaefer), where he habilitated in 1924 and became a privatdozent at University of Marburg.
He also conducted research there from 1946 to 1961 as an employee at the Marl Chemical Park.
Among other things, he researched on the direct proof of the dissociation of molecules by collisions of the second kind, the course of the reaction in the production of hydrogen and the electron affinity of oxygen.
[2] The Senftleben-Beenakker effects are named after him and Jan Beenakker, the influence of electric and magnetic fields on the transport properties (thermal conductivity, viscosity) of molecular gases.
