Sir John Sealy Edward Townsend (7 June 1868 – 16 February 1957) was a British physicist who conducted various studies concerning the electrical conduction of gases (concerning the kinetics of electrons and ions) and directly measured the electric charge of the electron. He served as the first Wykeham Professor of Physics at the University of Oxford from 1900 until 1941.
