S. Keith Runcorn, a British geophysicist, left an indelible mark on our understanding of Earth's magnetic field and its evolution. Born in Southport in 1922, Runcorn’s journey began with an engineering degree from Cambridge University in 1942. After contributing to radar research during World War II, he joined Manchester University, where his career truly took flight.
Runcorn's research interests were wide-ranging, encompassing various aspects of planetary magnetism, but he is most renowned for his pioneering work in paleomagnetism. This field studies the Earth's ancient magnetic field by examining the magnetic signatures preserved in rocks. Runcorn was instrumental in demonstrating that Earth's magnetic poles have wandered over geological time. He used this evidence to develop the theory of continental drift, which revolutionized our understanding of Earth's tectonic plates.
