Biography

change

Oliphant was born on October 8, 1901 in Kent Town, Adelaide, Australia. His father, Harold George “Baron” Oliphant, was a civil servant. His mother, Beatrice Edith Fanny Oliphant, was an artist.

After graduating from Adelaide High School in 1918, he was unable to get money to pay for university. He got a job cleaning floors at a jewelry store. He was soon able to study at the University of Adelaide. He was interested in medicine, but Kerr Grant, the physics professor, offered him a place in the Physics Department. He received his Bachelor of Science degree in 1921. Oliphant attempted to build a 60-inch (150-centimetre) cyclotron at the University of Birmingham. The completion of it was postponed by the World War II in Europe in 1939.

He was involved with the development of radar with John Randall and Harry Boot. They created a completely new design, the cavity magnetron, which made microwave radar possible.

His most important achievement was being involved with the development of the atomic bomb. He reported that it was possible, and achievable as early as 1943. He spread his research in the United States, which led to the development of the Manhattan Project, led by physicist J. Robert Oppenheimer.

Oliphant died on July 14, 2000 in Canberra, Australia.
