Joseph Nicollet’s Birthday 24 Jul 12

One of the earliest Europeans to explore Minnesota was born on this day in 1786 in France. Joseph Nicollet was known for the maps he published of the upper Mississippi River — and for the initials he and others engraved on the Pipestone quarries of southwestern Minnesota. He was a professor of mathematics and astronomer in France before emigrating to the United States in 1838. Nicollet’s name is applied to several places in the region he explored, including Nicollet County and the City of Nicollet
