At age 50, Draper again volunteered for military service, and was assigned a post with British military intelligence in India during in World War II. After the war, he returned to eugenicist and segregationist activism, and The Pioneer Fund supported the work of a number of noted and controversial researchers of race and intelligence, such as the Nobel Laureate William Shockley, American differential psychologist Arthur Jensen, Canadian evolutionary psychologist J. Philippe Rushton, and British anthropologist Roger Pearson. Though he never served as the Pioneer Fund's president, Draper remained on its board until his death, leaving his estate to the Fund. He also donated considerable funds to right-wing political organizations and candidates, including the World Anti-Communist League (WACL), which was later headed by Dr. Roger Pearson who had received extensive funding from The Pioneer Fund and Draper during his career at Southern Mississippi University.
