Keith Runcorn

Runcorn received many honours, including Fellowship of the Royal Society in 1965, the Gold Medal of the Royal Astronomical Society (RAS) and the Fleming medal of the American Geophysical Union (AGU). He was also a member of the Pontifical Academy of Science. In 1970 he was awarded the Vetlesen Prize, widely considered the highest honor in geology. In 1981, Runcorn became a founding member of the World Cultural Council. He served as the Sydney Chapman Endowed Chair in Physical Sciences at the University of Alaska from 1989 to 1995. In 2007 the RAS named an award – for the year's best PhD thesis in geophysics – the Keith Runcorn Prize in his honour.

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.

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.

(Stanley) Keith Runcorn FRS (19 November 1922 – 5 December 1995) was a British physicist whose paleomagnetic reconstruction of the relative motions of Europe and America revived the theory of continental drift and was a major contribution to plate tectonics.
