George Perkins MarshBorn 15 Mar 1801; died 23 Jul 1882 at age 81. American conservationist, whose book Man and Nature, or Physical Geography as Modified by Human Action (1864) was one of the 19th century's classic influences on geography, ecology, and resource management. Marsh demonstrated a remarkably wide range expertise in philology, etymology, the study of reptiles, engravings, music, the artificial propagation of fish, comparative grammar, physiognomy, and geography. Lewis Mumford was called "the fountain- head of the conservation movement" by Lewis Mumford. In his extensive touring of the Mediterranean world, Marsh became convinced that human civilization had remade the natural world but reshaped the face of nature with disastrous consequences. |
