Wolfgang Helfrich
Wolfgang Helfrich (born March 25, 1932) is a German physicist and inventor recognized for his contributions to twisted-nematic liquid crystal technology, which is used to produce a variety of modern LCD electronic displays.
== Career ==
Helfrich studied physics in Munich, Göttingen and Tübingen. Helfrich joined RCA in 1967, became interested in Charles-Victor Mauguin's twisted structure and thought it might be used to create an electronic display. However, RCA showed little interest because they felt that any effect that used two polarizers would also have a large amount of light absorption, requiring it to be brightly lit.
In 1970, Helfrich left RCA and joined the Central Research Laboratories of Hoffmann-LaRoche in Switzerland, where he teamed up with Swiss physicist Martin Schadt, a solid-state physicist. Schadt built a sample with electrodes and a twisted version of a liquid-crystal material called PEBAB (p-ethoxybenzylidene-p'-aminobenzonitrile), which Helfrich had reported in prior studies at RCA, as part of their guest-host experiments.
From 1973 until his retirement in 1997 Helfrich worked for Free University of Berlin.〔(Biophysics Prize Awarded to W. Helfrich and C. Bustamante )〕 Helfrich lives in Berlin.
