Frederick Seitz (July 4, 1911 – March 2, 2008) was an American physicist and a pioneer of solid state physics. Seitz studied under Eugene Wigner at Princeton University, graduating in 1934. He, along with Wigner, came up with the concept of the Wigner-Seitz unit cell used in the study of crystalline properties of materials. Seitz was president of the United States National Academy of Sciences (1962–1969).
