John C. Willke, American physician, author, and activist (born 1925)

John Charles Willke was an American author, physician, and anti-abortion activist. He served as president of National Right to Life and, along with his wife Barbara, authored a number of books on abortion and human sexuality. Willke was a leading promoter of the false claim that women's bodies resist pregnancy from forcible rape, an idea which continues to be promoted by some anti-abortion politicians.
