The American scientist Henry Fairfield Osborn (1857-1935) stood at the forefront of the debate over the evolution of man. Study of his theories, however, has been overshadowed by the perception that racism influenced his ideas. Henry Fairfield Osborn argues that his views were motivated by his science, itself grounded in religious doctrine. Osborn rejected ideas of primate ancestry and constructed his own non-Darwinian theory that human evolution was the long adventurous story of individuals and groups exerting personal will-power and inborn (...) characteristics to achieve both biological success and spiritual salvation. This biography charts Osborn's intellectual development, from a Christian childhood, through the influences of Arnold Guyot, James McCosh and T.H. Huxley, to his career at the American Museum of Natural History. (shrink)
