Sir Edward "Teddy" Crisp Bullard FRS (21 September 1907 – 3 April 1980) was a geophysicist who is considered, along with Maurice Ewing, to have founded the discipline of marine geophysics. He developed the theory of the geodynamo, pioneered the use of seismology to study the sea floor, measured geothermal heat flow through the ocean crust, and was one of the first to find new evidence for the theory of continental drift.
Bullard was born into a wealthy brewing family in Norwich, England. He was educated at Norwich School and later studied Natural Sciences at Clare College, Cambridge. He studied under Ernest Rutherford at the Cavendish Laboratory of University of Cambridge and in the 1930s he received his PhD degree as a nuclear physicist.
As it was the Great Depression and he was married he had to find a career to survive on. In the 1930s nuclear physics did not seem to be it so he switched to geophysics. During World War II he was an experimental officer at HMS Vernon, and worked on the development of degaussing techniques to protect shipping from magnetic mines.
Bullard held a chair at the University of Toronto from 1948–50 and was head of the National Physical Laboratory between 1950 and 1955. He returned to Cambridge in 1955, first as an assistant in research, then as a Reader and finally to a chair created for him in 1964. He was a founding fellow of Churchill College, Cambridge
