Description: (Meteorologist)
Group Captain James Martin Stagg, a British Met Office meteorologist with the Royal Air Force during World War II, was pivotal in convincing General Dwight D. Eisenhower to postpone the date of the Allied invasion of Europe from 5 to 6 June 1944. Stagg's proficiency in weather forecasting and his precise forecasts of a brief respite in inclement weather were crucial to the triumph of the D-Day operation. His lasting impact on military meteorology and strategic decision-making is evident through his substantial contributions.
