Donald Norton Yates
Donald Norton Yates (November 25, 1909 – August 28, 1993) was the US Army Air Force officer who helped select June 6, 1944 as the date for D-Day, the Allied invasion of Europe, in his capacity as chief meteorologist on General Dwight D. Eisenhower's staff. Yates and his British counterpart, James Martin Stagg, chose well – it turned out to be the only day that month the English Channel could have been successfully crossed.
