Leonard Isaac Schiff was born in Fall River, Massachusetts on March 29, 1915 and died on January 21, 1971 in Stanford, California. He was a physicist best known for his book Quantum Mechanics.
Leonard Schiff entered Ohio State University at age 14. Schiff received his B.S. & M.S. (working under L. H. Thomas) from Ohio State University and his doctorate from Massachusetts Institute of Technology in 1937 under Philip M. Morse with thesis Theory of the Collision of Light Elements.
Schiff was a theoretical physicist who, after completing his doctorate, worked as a research associate for two years at the University of California and the California Institute of Technology. From 1940-1945 he was a faculty member at the University of Pennsylvania. From 1945-1947, he worked at Los Alamos Scientific Laboratory and joined the physics faculty at Stanford University in 1947.
In 1948, Schiff became one of the initial directors of Varian Associates who provided technical support to the company, along with Edward Ginzton, William Hansen, and Marvin Chodorow.
In the late 1959 and 1960 Schiff and fellow physicist George Pugh wrote papers which advocated using orbiting gyroscopes to test general relativity. Schiff teamed with fellow Stanford faculty Bob Cannon and Bill Fairbank to conduct research that provided part of the foundation for the Gravity Probe B (GP-B) to test Einstein's theory of relativity.
