Grand Canyon: A Different View features essays by  which American biochemist and a prominent member of the creationist movement?
Duane Gish Duane Tolbert Gish (February 17, 1921 – March 5, 2013) was an American biochemist and a prominent member of the creationist movement. A Young Earth creationist, Gish was a former vice-president of the Institute for Creation Research (ICR) and the author of numerous publications about creation science. Gish was called "creationism's T. H. Huxley" for the way he "relished the confrontations" of formal debates with prominent evolutionary biologists, usually held on university campuses. A creationist publication noted in his obituary that "it was perhaps his personal presentation that carried the day. In short, the audiences liked him."
Edward Drinker Cope Edward Drinker Cope (July 28, 1840 – April 12, 1897) was an American paleontologist and comparative anatomist, as well as a noted herpetologist and ichthyologist. He was a founder of the Neo-Lamarckism school of thought. Born to a wealthy Quaker family, Cope distinguished himself as a child prodigy interested in science; he published his first scientific paper at the age of 19. Though his father tried to raise Cope as a gentleman farmer, he eventually acquiesced to his son's scientific aspirations. Cope married his cousin and had one child; the family moved from Philadelphia to Haddonfield, New Jersey, although Cope would maintain a residence and museum in Philadelphia in his later years.
