College professor, to form "a unified front against the theory of evolution." There were three main schools of creationist thought, represented by Price, Rimmer, and tidal expert William Bell Dawson. However, since Dawson was a proponent of day-age creationism and Rimmer was ardently convinced that gap creationism was correct, the staunch supporters of a literal 6 day creation and 6000-year-old earth were incensed, and the organization fell apart.H. W. Clark to G. M. Price, 12 September 1937 (Price Papers) Price and his supporters retreated to California, and with several doctors working at the College of Medical Evangelists (now Loma Linda University), formed the "Deluge Geology Society." The "Deluge Geology Society" published the Bulletin of Deluge Geology and Related Science from 1941 to 1945. They made secret plans to unveil discoveries of fossils of human footprints that were in rock that was purportedly older than accounted for in evolutionary theory. However, again the organization foundered over disagreements about a 6000 year old earth. Price was particularly strident in his attacks against fellow creationists. His friend and former student Harold W. Clark had earned a master's degree in biology from the University of California, Berkeley, and felt that Price's book New Geology was "entirely out of date and inadequate." Unfortunately, Price responded angrily when he found out, accusing Clark of suffering from "the modern mental disease of universityitis" and of falling in with the "tobacco-smoking, Sabbath-breaking. God-defying" evolutionists. Clark pleaded with Price that he still believed in a 6 day creation and a young earth and a universal flood, but Price responded with a vitriolic publication entitled Theories of Satanic Origin about Clark and his views. The American George Gaylord Simpson argued that the paleontological record supported evolution in the 1940s. Some creationists, however, objected to his supposed equation of microevolution and macroevolution, acknowledging the former but denying the latter, and continue to do so to this day. Post-war United States The Second World War (1939–1945) saw the horrors of the Nazi Holocaust. American creationist explanation for the Holocaust is that it had been driven in part by eugenics, or the principle that individuals with "undesirable" genetic characteristics should be removed from the gene pool. Eugenics was based in part on principles of cultural evolutionary theory, though many biologists had long opposed it. Although eugenics was rejected by other nations after the war, the memory of it did not quickly fade, and
