Ronald William Clark (2 November 1916 – 9 March 1987) was a British author of biography, fiction and non-fiction.
Born in London, Clark was educated King's College School. In 1933, he embarked on a career as a journalist, and served as a war correspondent during the Second World War after being turned down for military service on medical grounds. As a war correspondent, Clark landed on Juno Beach with the Canadians on D-Day. He followed the war until the end, and remained in Germany to report on the major War Crimes trials.
After returning to Britain in 1948, Clark embarked on a career as an author. He wrote extensively on subjects ranging from mountain climbing (over a dozen titles), the atomic bomb, Balmoral Castle, and world explorers, as well as novels of alternate history. He also wrote a number of biographies of a diverse range of historical figures, including: Charles Darwin, Thomas Edison, Albert Einstein, Benjamin Franklin, Sigmund Freud, J.B.S. Haldane, V. I. Lenin, Bertrand Russell, Ernst Chain, Edward Appleton and William F. Friedman. V. I. Lenin was Clark's last biography and came out the year following his death.
