Frederic Andrews Gibbs (1903–1992) was an American neurologist who was a pioneer in the use of electroencephalography (EEG) for the diagnosis and treatment of epilepsy. Gibbs graduated from Yale and Johns Hopkins in 1929. He was offered a fellowship in neuropathology by Stanley Cobb, of Harvard Medical School. He studied epilepsy in the same laboratory as William G. Lennox and Erna Leonhardt. In 1944, they moved to University of Illinois School of Medicine, and Frederic Gibbs was promoted to professor in the epilepsy clinic. Erna Gibbs died in 1987.
