## History

This settlement, first platted on June 12, 1839, was originally named "Newton" and was established at the rapids of the Iroquois River. By 1844, it had been renamed "Rensselaer", after James Van Rensselaer, a merchant from Utica, New York, who came to the area after his business failed in the Panic of 1837. He took over the land from Joseph D. Yeoman, who had established a farm some years earlier and had begun to plan the village.
St. Joseph Indian Normal School was established in 1888 by St. Katherine Drexel, an heiress from Philadelphia, who donated $50,000 for the education of Catholic American Indian boys. The school trained 60 boys annually until 1896. The school was operated by the Bureau of Catholic Indian Missions.
In addition to St. Joseph Indian Normal School, the Jasper County Courthouse, Oren F. and Adelia Parker House, Rensselaer Carnegie Library, and Rensselaer Courthouse Square Historic District are listed on the National Register of Historic Places.
