Thomas Eugene Everhart FREng (born February 15, 1932, Kansas City, Missouri) is an American educator and physicist. His area of expertise is the physics of electron beams. Together with Richard F. M. Thornley he designed the Everhart–Thornley detector. These detectors are still in use in scanning electron microscopes, even though the first such detector was made available as early as 1956.
Everhart was elected a member of the National Academy of Engineering in 1978 for contributions to the electron optics of the scanning electron microscope and to its use in electronics and biology. He was appointed an International Fellow of the Royal Academy of Engineering in 1990. He served as chancellor of the University of Illinois at Urbana-Champaign from 1984 to 1987 and as the president of the California Institute of Technology from 1987 to 1997.
