Rene Robert Cavelier, Sieur de La Salle
Born Rouen, France, 1643; died Texas, 1687.
At the age of twenty-three he went to Canada as an adventurer and trader.
In 1669 he left Montreal on an expedition concerning which little is known; he is said to have been the first white man to have gazed on Niagara and to have explored the Ohio River.
He erected Fort Frontenac on Lake Ontario and, 1678, passed through Lakes Erie, Huron, and Michigan, reached the Illinois, founded Fort Crevecreur and returned on foot to Montreal.
Later he attempted to found a French colony near the mouth of the Mississippi, but was assassinated by mutineers.
