The school was founded in 1866, when the Minnesota Conference of Congregational Churches unanimously accepted a resolution to locate a college in Northfield. Two Northfield businessmen, Charles Augustus Wheaton and Charles Moorehouse Goodsell, each donated of land for the first campus. The first students enrolled at the preparatory unit of Northfield College in the fall of 1867. In 1870, the first college president, James Strong, traveled to the East Coast to raise funds for the college. On his way from visiting a potential donor, William Carleton of Charlestown, Massachusetts, Strong was badly injured in a collision between his carriage and a train. Impressed by Strong's survival of the accident, Carleton donated $50,000 to the fledgling institution in 1871. As a result, the Board of Trustees renamed the school in his honor.
