Charles Lyell (1797–1875) was a Scottish geologist and author, best known for his influential work in the field of geology. His most famous book, "Principles of Geology," published in three volumes between 1830 and 1833, introduced the theory of uniformitarianism, which suggested that the Earth's features were shaped by slow, gradual processes over vast periods of time.
