Amherst College is a private liberal arts college in Amherst, Massachusetts, founded in 1821 as the Amherst Collegiate Institution by Zephaniah Swift Moore, former president of Williams College, initially for the classical education of indigent young men intended for the Christian ministry with strong Calvinist ties though non-sectarian. It received its charter from the Massachusetts Legislature in 1825, with the first class graduating in 1826, and is named after British commander Jeffery Amherst. One of the most selective liberal arts colleges in the United States, it became coeducational in 1975 after a trustee vote (15-3), admitting 94 women that fall. The campus spans 1,000 acres, and it offers bachelor's degrees in 43 fields across arts, humanities, natural sciences, and social sciences through an open curriculum. The motto is 'Terras Irradient' ('Let them give light to the world'). Notable historical firsts include hosting the world's first intercollegiate baseball game against Williams in 1859, establishing the first collegiate physical education and hygiene program in 1860, and launching the nation's first undergraduate neuroscience program in 1973. It has hosted faculty such as Robert Frost (intermittently from 1916) and Niels Bohr lectures (1923). Alumni include U.S. President Calvin Coolidge (class of 1895). The current student-faculty ratio is 7:1. Amherst aims for climate neutrality by 2030 and is recognized as a Tree Campus, as well as a top Fulbright producer.
