Casimir Pulaski was born in Poland in 1745. After proving his military mastery in independence struggles across Europe, Pulaski moved to Boston in 1777. He formed the colonists' first legion on horseback, became Brigadier General and saved George Washington's retreating troops at Brandywine. Pulaski was later mortally wounded, and died, amid the 1779 Siege of Savannah. But for centuries, his final resting place remained a mystery.
Earlier this month, the Smithsonian Channel revealed not only that the "father of the American cavalry" was indeed buried in Savannah – but also that Pulaski may biologically been intersex. Both breakthroughs came after decades of research by a team based in Georgia with help from colleagues across the United States, Poland and Canada.
