(now Lviv, Ukraine) was then in the Austro-Hungarian Empire; from 1918 until 1939 was in the Second Polish Republic. Jews and the US Navy Commodore Uriah P. Levy Uriah Phillips Levy (1792–1862) was the first Jewish-American Commodore of the United States Navy and a veteran of the War of 1812. At the time, Commodore was the highest rank obtainable in the U.S. Navy and would be roughly equivalent to the modern-day rank of Admiral. During his tenure, he ended the Navy's practice of flogging, and prevailed against the antisemitic bigotry he faced among his fellow naval officers. His service is memorialized through the Commodore Uriah P. Levy Center and Jewish Chapel at the US Naval Academy at Annapolis. Admiral Hyman G. Rickover Hyman George Rickover (1900–1986), was born to Abraham Rickover and Rachel (née Unger) Rickover, a Jewish family in Maków Mazowiecki Poland, at that time under Russian rule. He rose to a four-star admiral in the United States Navy who directed the original development of naval nuclear propulsion and controlled its operations for three decades as director of Naval Reactors. He was known as the "Father of the Nuclear Navy", which as of July 2007 had produced 200 nuclear-powered submarines, and 23 nuclear-powered aircraft carriers and cruisers. With his unique personality, political connections, responsibilities, and depth of knowledge regarding naval nuclear propulsion, Rickover became the longest-serving naval officer in U.S. history with 63 years active duty. Admiral Jeremy Michael Boorda Jeremy Michael Boorda (1939–1996) was an admiral of the United States Navy and the 25th Chief of Naval Operations (CNO). Boorda is the only CNO to have risen to the position from the enlisted ranks. He was born on November 26, 1939, in South Bend, Indiana, to a Jewish family. He grew up in Chicago, Illinois. He dropped out of high school when he was seventeen years old and joined the Navy. This was the beginning of his naval career of 40 years. Boorda kept his Jewish roots private: "Although Boorda was not a practicing Jew and in fact raised his children as Protestants, he was born to two Jewish parents and had a bar mitzvah. He did not in any way emphasize his Jewish roots or his Jewishness, said Rabbi Aaron Landes, a retired U.S. Navy rear admiral ... virtually no one knew that Boorda, who became the first enlisted man to rise to the Navy's highest post
