Education and early life
Runcorn was born in Southport, Lancashire, and educated at King George V Grammar School and Gonville and Caius College, Cambridge, whence he graduated in engineering within two years in 1942. After a period in radar research during the World War II, he joined the Physics Department at the University of Manchester where he did research on aspects of the Earth's magnetic field, taking his PhD for research supervised by Patrick Blackett in 1949.

Career and research
Runcorn's PhD led to his interest in palaeomagnetism, the study of the magnetism of rocks, which he pursued first at the Geophysics Department at the University of Cambridge and later at Newcastle University, where he was appointed to the chair of Physics in 1956. At Newcastle, Runcorn developed a strong research group in geophysics, and made substantial contributions to various fields, including convection in the Earth and Moon, the shape and magnetic fields of the Moon and planets, magnetohydrodynamics of the Earth's core, changes in the length of the day, polar wandering, continental drift and plate tectonics. After his retirement in 1988 he continued to be active in various lines of research until his untimely death in San Diego in 1995.

Death
Runcorn was murdered in his hotel room in San Diego during a lecture trip to the Scripps Institution of Oceanography. Police found that he had been strangled and found evidence of injuries to the head. Paul Cain, a professional kick-boxer, was later convicted and sentenced to a term of at least 25 years. Prosecutors argued that Cain killed Runcorn after stealing his wallet and credit cards, having targeted him as an elderly gay man and therefore easy victim. Cain was tried three times in all. The first trial ended with a deadlocked jury; the second with a conviction that was overturned on appeal, on grounds that testimony from Cain's two previous wives as to his violent temper should not have been admitted in evidence.
