Other scientists such as Georges Cuvier (1769–1832) put forward ideas of past ages, and geologists such as Adam Sedgwick (1785–1873) incorporated Werner's ideas into concepts of catastrophism; Sedgwick inspired his university student Charles Darwin to exclaim "What a capital hand is Sedgewick [sic] for drawing large cheques upon the Bank of Time!". In a competing theory, Charles Lyell in his "Principles of Geology" (1830–1833) developed Hutton's comprehension of endless deep time as a crucial scientific concept into uniformitarianism. As a young naturalist and geological theorist, Darwin studied the successive volumes of Lyell's book exhaustively during the "Beagle" survey voyage in the 1830s, before beginning to theorise about evolution.
