Thaddeus Kosciuszko, a Polish (imagine that!) noble, was one of an amazing number of European nobles who helped lead the American Revolution -- aimed at ending rule by nobility. Kosciuszko directed the building of fortifications that defended Saratoga and West Point, and developed combat engineering techniques that provided roads for General Washington's army, and escape routes for General Nathan Greene. He returned to Poland after the revolution, and was a leader in what has become known as Kosciuszko's Uprising -- which was crushed flat by Prussia and Russia. He died in exile in Switzerland.
