St. Isaac Jogues, S.J. was a Jesuit priest, missionary and martyr who traveled and worked among the Iroquois, Huron, and other Native populations in North America. He was the first European to name Lake George, calling it Lac du Saint Sacrement . In 1646, Jogues was martyred by the Mohawk at their village of Ossernenon, south of the Mohawk River.
Issac Jogues was born on January 10, 1607, in Orlans, France, into a bourgeois family, where he was the fifth of nine children. He was educated at home until the age of ten, at which point he began attending Jesuit schools. In 1624, at the age of seventeen, he entered the Jesuit novitiate at Rouen in Northern France. Here, his Master of Novices was Louis Lallemant. The master, Louis Lallement, already had two brothers and a nephew serving as missionaries in the colony of New France.
