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. Yates was subsequently decorated by three governments. He went on to become the chief meteorologist of the newly formed U.S. Air Force, and Commander of the Air Force Missile Test Center at Patrick Air Force Base in Florida.
