H. de la BECHE - ProfIchthyosaurus - 1830

One of the most famous caricatures, depicted many times in books dealing with geology and palaeontology, was produced by the English geologist Henry De la Beche (1796-1855) to lampoon the theories of Charles Lyell. The prominent "Professor Ichthyosaurus" was considered first to represent William Buckland (1784-1856), but the geologist and dedicated earth-science historian Martin J.S. Rudwick realized the connection of this scene with some drawings produced in 1831 by De la Beche in his diary, where he ridiculed the uniformity-principle of Lyell.
