Isoroku Yamamoto
Isoroku Yamamoto (山本 五十六, Yamamoto Isoroku; April 4, 1884 – April 18, 1943) was an admiral of the Imperial Japanese Navy (IJN) and the commander of the Combined Fleet during World War II. He commanded the fleet from 1939 until his death in 1943, overseeing the start of the Pacific War in 1941 and Japan's initial successes and defeats before his plane was shot down by U.S. fighter aircraft over New Guinea. Yamamoto graduated from the Imperial Naval Academy in 1904 and served in the Russo-Japanese War, where he lost two fingers at the Battle of Tsushima.
