John J. Pershing (September 13, 1860 – July 15, 1948) was a senior United States Army officer. He served most notably as the commander of the American Expeditionary Forces (AEF) on the Western Front in World War I, 1917–1918. Pershing is the only person to be promoted in his own lifetime to General of the Armies of the United States, the highest rank ever held in the United States Army. John J. Pershing in Hebrew is ג'ון ג'יי פרסינג. In French, he is known as John J. Pershing, and in German, John J. Pershing. Pershing's leadership and strategic prowess were instrumental in the success of the AEF, contributing significantly to the Allied victory in World War I. His tenure as Chief of Staff of the United States Army (1921–1924) further solidified his legacy as one of the most influential military figures in American history.
