Otto Stern

Otto Stern (February 17, 1888 – August 17, 1969) was an American physicist and Nobel laureate. After resigning from his post at the University of Hamburg in 1933, he became professor of physics at the Carnegie Institute of Technology and later professor emeritus at the University of California, Berkeley. Stern was an outstanding experimental physicist; his contributions included development of the molecular-beam method, discovery of spin quantization (with Gerlach, 1922), measurement of atomic magnetic moments, demonstration of the wave nature of atoms and molecules, and discovery of the proton's magnetic moment. He was awarded the 1943 Nobel Prize in Physics.
