Georges Guynemer (December 24, 1894 - September 11, 1917) was a French aviator during World War I.

Georges Marie Ludovic Jules Guynemer was born into a wealthy Compiègne family and experienced an often sickly childhood. Nevertheless, he succeeded in aviation through his enormous drive and self confidence. He was originally rejected for military service but was accepted for mechanic training in late 1914. With characteristic determination he gained acceptance to pilot training, joining Escadrille MS.3 in June 1915. He flew Morane Saulnier types, experiencing both victory and defeat (in all, he was shot down seven times.)

Upon joining the elite Escadrille N.3 in 1916, Guynemer quickly established himself as one of France's premier fighter pilots. He became an ace with his fifth victory in February 1916 and was promoted to lieutenant in March. At year end his score had risen to 25. Less than a year later he was a captain and commander of the Storks squadron . His greatest month was May 1917 when he downed seven German aircraft, and he became the first French ace to attain 50 victories at the end of July.

Guynemer disappeared on 11 September 1917. Separated from his wingman, apparently he attacked a German observation plane and was killed in the ensuing combat. His body was never found but the Germans claimed that he had been shot down by Kurt Wissemann of Jasta 3. At the time of his death Guynemer had achieved 53 victories.

Guynemer's death was a profound shock to France, but he remained an icon for the duration of the war. Only age 22, he continued inspiring the nation with his comment, "Until one has given all, one has given nothing."
