description Harold Jeffreys Overview
Sir Harold Jeffreys (1891–1989) was a highly influential British mathematician, statistician, and geophysicist whose work significantly shaped modern seismology. Alongside Keith Edward Bullen, he co-compiled the Jeffreys–Bullen travel-time tables, which accurately detail the time it takes for seismic waves to travel through the Earth and remain a standard tool for earthquake location. Although he made pioneering contributions to the understanding of Earth's internal structure, Jeffreys was also known for his staunch, long-standing opposition to the theory of continental drift.

What is Harold Jeffreys most famous for in geology?
Sir Harold Jeffreys is famous for co-compiling the Jeffreys–Bullen travel-time tables alongside Keith Edward Bullen. These tables accurately detail the time it takes for seismic waves to travel through the Earth, forming the foundation of modern seismology.
Did Harold Jeffreys believe in continental drift?
No, Harold Jeffreys was famously a staunch opponent of the theory of continental drift. He mathematically argued that the mantle of the Earth was too rigid for the continents to move across it, which set back the acceptance of plate tectonics until the 1960s.
What awards did Harold Jeffreys receive for his scientific work?
Jeffreys received numerous prestigious honors, including the Royal Society's Copley Medal in 1961 and the Wollaston Medal. He was also knighted in 1953 for his immense contributions to geophysics and statistics.
When did Harold Jeffreys live and work?
