He was born in Fatfield, County Durham, England. He studied at Armstrong College in Newcastle upon Tyne, then part of the University of Durham, and with the University of London External Programme.^[1] He then went to St John's College, Cambridge and became a fellow in 1914. At Cambridge University he taught mathematics, then geophysics and finally became the Plumian Professor of Astronomy.
He married another mathematician and physicist, Bertha Swirles (1903-1999), in 1940 and together they wrote ''Methods of Mathematical Physics''.
Among his other contributions was a Bayesian approach to probability (also see Jeffreys prior), and the idea that the Earth's planetary core was liquid. He was knighted in 1953.
Jeffreys received the Gold Medal of the Royal Astronomical Society in 1937.
