Gray was born in Sauquoit, N.Y. in 1810 and educated at the College of Physicians and Surgeons in Fairfield (Ph.D., 1831). He taught at Utica Gymnasium, 1832-1834; Hamilton College, 1834; University of Michigan, 1838-1842; and Harvard University, 1842-1873. Gray established systematic botany at Harvard; his herbarium became the nucleus of the Gray Herbarium at Harvard; and he also wrote several botanical textbooks such as Manual of the Botany of the northern United States. In 1848 Gray married Jane Loring who accompanied him on most of his travels and chronicled them in her letters to her family. After Gray's death in 1888 she prepared an edition of his letters which was published in 1893.
