Charles Darwin

Charles Robert Darwin, was an English naturalist, geologist and biologist, best known for his contributions to the science of evolution. His proposition that all species of life have descended over time from common ancestors is now widely accepted, and considered a foundational concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process that he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding.

Barry Voight

Barry Voight is an American geologist, volcanologist, author, and engineer. After earning his Ph.D. at Columbia University, Voight worked as a professor of geology at several universities, including Pennsylvania State University, where he taught from 1964 until his retirement in 2005. He remains an emeritus professor there and still conducts research, focusing on rock mechanics, plate tectonics, disaster prevention, and geotechnical engineering.

Eugene Merle Shoemaker

Eugene Merle Shoemaker, also known as Gene Shoemaker, was an American geologist and one of the founders of the field of planetary science. He is best known for co-discovering the Comet Shoemaker–Levy 9 with his wife Carolyn S. Shoemaker and David H. Levy. This comet hit Jupiter in July 1994: the impact was televised around the world.

George de Mohrenschildt

George Sergius de Mohrenschildt was a petroleum geologist and professor who befriended Lee Harvey Oswald in the summer of 1962 and maintained that friendship until Oswald's death, two days after the assassination of US President John F. Kennedy. His testimony before the Warren Commission investigating the assassination was one of the longest of any witness.

Science

James Hutton

James Hutton was a Scottish geologist, physician, chemical manufacturer, naturalist, and experimental agriculturalist. He originated the theory of uniformitarianism—a fundamental principle of geology—that explains the features of the Earth's crust by means of natural processes over geologic time. Hutton's work established geology as a science, and as a result he is referred to as the "Father of Modern Geology".

Charles Lyell

Sir Charles Lyell, 1st Baronet, was a Scottish geologist who popularised the revolutionary work of James Hutton. He is best known as the author of Principles of Geology, which presented uniformitarianism–the idea that the Earth was shaped by the same scientific processes still in operation today–to the broad general public. Principles of Geology also challenged theories popularised by Georges Cuvier, which were the most accepted and circulated ideas about geology in Europe at the time.

Kathryn D. Sullivan

Kathryn Dwyer Sullivan is an American geologist and a former NASA astronaut. A crew member on three Space Shuttle missions, she was the first American woman to walk in space on October 11, 1984. She was Under Secretary of Commerce for Oceans and Atmosphere and Administrator of the National Oceanic and Atmospheric Administration after being confirmed by the U.S. Senate on March 6, 2014. Sullivan's tenure ended on January 20, 2017 with the swearing in of President Donald Trump. Following completion of her service at NOAA, she was designated as the 2017 Charles A. Lindbergh Chair of Aerospace History at the Smithsonian Institution’s National Air and Space Museum., and has also served as a Senior Fellow at the Potomac Institute for Policy Studies.

Arthur Holmes

Prof Arthur Holmes FRS FRSE LLD 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.
