AnswerCharles Lyell, lawyer and geologist who developed the theory of uniformitarianism in geology is commonly recognised as the one person who had the most profound influence on Darwin. Captain Fitzroy with whom Darwin sailed on his famous voyage on the Beagle, gave Darwin a copy of Lyell's 'Principles of Geology'. It is difficult to say who had the second greatest influence, but certainly his grandfather Erasmus Darwin, who himself wrote on Evolution had a great influence.
