Sir Charles Lyell lived from November 14, 1797 to February 22, 1875 and was a Scottish geologist who popularized the work of James Hutton. His best known work The Progress of Geology presented uniformitarianism. This is the theory that the Earth was shaped by the same scientific processes still in operation through present day.
Among his scientific contributions was an explanation of earthquakes, a theory of volcanoes, the division of the Tertiary period into the Pilocene, Miocene, and Eocene. He is also the scientist who coined the Palaeozoic, Mesozoic and the Cenozoic.
Lyell followed deistic beliefs and believe the earth to be very ancient. As a close friend to Charles Darwin he contributed to Darwin’s thinking on evolution.
