Robert Wichard Pohl (10 August 1884 – 5 June 1976) 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 (also called color 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 (Pohl wheel) are named after him.
