Arthur Holmes FRS (14 January 1890 – 20 September 1965) was a British geologist who made two major contributions to the understanding of geology. He pioneered the use of radioactive dating of minerals and was the first earth scientist to grasp the mechanical and thermal implications of mantle convection, which led eventually to the acceptance of plate tectonics.
