From Wikipedia, the free encyclopedia
Otto Lehmann (born January 13, 1855 in Konstanz, Germany; died June 17, 1922 in Karlsruhe) was a famous German physicist and "father" of liquid crystal technology.
Between 1872 and 1877, Lehmann studied natural sciences at the University of Straßburg and made Ph.D. under Paul Groth. Initially becoming a school teacher for physics, mathematics and chemistry in Mülhausen (Elsass), he starts university teaching at the prestigious RWTH Aachen University in 1883. In 1889, he succeeds Heinrich Hertz as head of the Institute of Physics in Karlsruhe.
Since 1912, Lehmann repeatedly was a candidate for a Nobel Prize, but was never awarded one.
