Born in Dumbarton, New Hampshire in 1815, Hoyt received his undergraduate education at Yale University, where he was a member of Skull and Bones. After Hoyt's graduation from Yale in 1840, he served as an instructor in mathematics and natural philosophy at Phillips Exeter Academy from 1840 to 1858, before taking up his post at Washington University. In 1862, Hoyt died in St. Louis, Missouri at the age of 47.
