Pryce was born in Croydon to an Anglo-Welsh father and French mother, and in his teens attended the Royal Grammar School, Guildford. After a few months in Heidelberg to add German to the French that had been his first language at home, he went up to Trinity College, Cambridge. In 1935 he went to Princeton University, supported by a Commonwealth Fund Fellowship (now Harkness Fellowship) where he worked with Wolfgang Pauli and John von Neumann, obtaining his Ph.D. with a thesis on The wave mechanics of the photon. In 1937 he returned to England as a Fellow of Trinity, until in 1939 he was appointed Reader in Theoretical Physics at Liverpool University under James Chadwick. In 1941 he joined the Admiralty Signals Establishment (now part of the Admiralty Research Establishment) to work on radar. In 1944 he joined the British atomic energy team in Montreal designing nuclear reactors, but in 1945 returned to England, first to Cambridge and then in 1946 to Oxford, where he was appointed Wykeham Professor of Physics. Among of his doctoral students were Anatole Abragam and John Clive Ward. In 1950, when Klaus Fuchs, head of the theoretical physics group at AERE, Harwell, was arrested for supplying atomic secrets to the USSR, Maurice also served part-time as his replacement. In 1954 he moved to the University of Bristol as Head of the Physics Department. In 1964 he went back to North America, first to the University of Southern California and then in 1968 to the University of British Columbia. From 1968 to 1978 he served on the Technical Advisory Committee (for nuclear waste management) of Atomic Energy of Canada Limited.
