Rene-Robert Cavelier was a celebrated French explorer, known for his expeditions to the New World in the 17th century. Some common synonyms for his name include Robert de La Salle, Sieur de La Salle, or simply La Salle. He was also sometimes referred to by his nickname "Iron Hand" due to a metal prosthetic hand that he was said to have worn. La Salle was instrumental in establishing French colonisation in North America, claiming territory for France that later became parts of modern-day Illinois, Indiana, and Texas. Despite his many accomplishments, La Salle's life was cut tragically short when he was assassinated by members of his own expedition in 1687.
