 school in Birmingham, going from there to Clare College, Cambridge to read mathematics, graduating in 1933. He was elected a Fellow of St John's College in 1937 and appointed a lecturer in mathematics in the same year (until 1959). He was Reader in Theoretical Astronomy from 1959 to 1969, after which he was appointed to a specially created professorship in the subject.

Author of numerous papers on the origin and early history of the Solar System, notably his modifications of the collision theory. Showed from work of Cartan that fission of a planet by rotation would give two independent bodies, and consequently that the fission theory of binary stars is untenable (The Stability of Rotating Liquid Masses, 1953). Author (with F. Hoyle) of numerous papers on the astronomical effects of accretion, and (with H.
