Arthur Holmes
Arthur Holmes FRS[1] (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 radiometric 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 -

Alfred Wegner
Alfred Lothar Wegener (1 November 1880 – November 1930) was a German polar researcher, geophysicist and meteorologist. During his lifetime he was primarily known for his achievements in meteorology and as a pioneer of polar research, but today he is most remembered as the originator of the theory of continental drift by hypothesizing in 1912 that the continents are slowly drifting around the Earth (Kontinentalverschiebung). His hypothesis was controversial and not widely accepted until the 1950 -
Harry Hess
Harry Hammond Hess (May 24, 1906 – August 25, 1969) was a geologist and United States Navy officer in World War II. Considered one of the "founding fathers" of the unifying theory of plate tectonics, Rear Admiral Harry Hammond Hess was born on May 24, 1906 in New York City. He is best known for his theories on sea floor spreading, specifically work on relationships between island arcs, seafloor gravity anomalies, and serpentinized peridotite, suggesting that the convection of the Earth's mantle
