About this person
Robert Wichard Pohl was a German physicist and professor of the University of Göttingen. The physical institute in Göttingen led by Pohl was one of the first schools in solid state physics and Nevill Francis Mott described Pohl as the "father of solid state physics.". He is known for relating color in alkali metal halides with the presence of vacancies and F-centers, a type of crystallographic defect. He also demonstrated the first transistor based on color centers. The Gudden-Pohl effect and the Pohl torsion pendulum are named after him.
