John Stuart Foster

John Stuart Foster (May 30, 1890 – September 9, 1944) was a Canadian physicist.

Born in Clarence, Nova Scotia, Canada, he completed his Ph.D. at Yale University with a dissertation on the first measurements of the Stark effect in Helium. In 1924 he gained an appointment as assistant professor at McGill University in Montreal where he taught physics. He became associate professor in 1930.

During the Second World War he served as a liaison officer for the National Research Council, working at the MIT radiation laboratory on radar research and development. He developed a fast-scan radar antennae that became known as the "Foster scanner".

He returned to McGill in 1944, where he directed the construction of a 100-MeV cyclotron. This instrument was commissioned in 1949. At the time this was the second largest in the world. From 1952 until 1954 he was Chairman of the Physics Department at McGill. He died in Berkeley, California.

His son, John Stuart Foster Jr., graduated from the University of California in 1948, then became director of the Lawrence Livermore National Laboratory, director of Defense Research and Engineering for the U.S. Defense Department, and Vice President of T.R.W., Inc.
