British lawyer and the foremost geologist of his day. He is best known as the author of Principles of Geology, which popularised James Hutton's concepts of uniformitarianism – the idea that the earth was shaped by the same processes still in operation today. Lyell was a close and influential friend of Charles Darwin.

"In his religious views, Lyell was essentially a deist, holding the position that God had originally created the world and life on it, and then had allowed nature to operate according to its own (God-given) natural laws, rather than constantly intervening to direct and shape the course of all history."
