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."
