Casimir Pulaski, Polish-American general (b. 1745)
Kazimierz Michał Władysław Wiktor Pułaski of Ślepowron (Polish pronunciation: [kaˈʑimjɛʐ puˈwaskʲi] (listen); Casimir Pulaski ; March 4 or March 6, 1745 – October 11, 1779) was a Polish-American nobleman, soldier and military commander who has been called, together with his counterpart Michael Kovats de Fabriczy, "the father of the American cavalry."

Born in Warsaw and following in his father's footsteps, he became interested in politics at an early age. He soon became involved in the military and in revolutionary affairs in the Polish–Lithuanian Commonwealth. Pulaski was one of the leading military commanders for the Bar Confederation and fought against the Commonwealth's foreign domination. When this uprising failed, he was driven into exile. Following a recommendation by Benjamin Franklin, Pulaski traveled to North America to help in the American Revolutionary War. He distinguished himself throughout the revolution, most notably when he saved the life of George Washington. Pulaski became a general in the Continental Army, and he and his friend, Michael Kovats, created the Pulaski Cavalry Legion and reformed the American cavalry as a whole. At the Battle of Savannah, while leading a cavalry charge against British forces, he was fatally wounded by grapeshot and died shortly after.

Pulaski is remembered as a hero who fought for independence and freedom in Poland and the United States. Numerous places and events are named in his honor, and he is commemorated by many works of art. Pulaski is one of only eight people to be awarded honorary United States citizenship. Analyses since the 1990s of Pulaski's presumed remains have raised the possibility that Pulaski was biologically intersex.
