(1785–1872), army engineer and putative “Father of the Military Academy.”
A native of Braintree, Massachusetts, Thayer attended Dartmouth for three years, then entered West Point, graduating in 1808. After coastal fortification service and participation in the War of 1812, he spent two years in Europe studying military institutions. He became superintendent of the U.S. Military Academy in 1817. Backed by Secretary of War John C. Calhoun, Thayer overhauled the academic and disciplinary systems. His reforms included organizing the corps of cadets into a battalion, establishing an academic board to oversee curricular matters, dividing classes into sections according to merit, and holding semiannual examinations. He also recruited several professors who achieved distinction, especially Dennis Hart Mahan. After a dispute with President Andrew Jackson Thayer, resigned his office in 1833 and returned to coastal fortification duty. Upon retirement, he established an engineering school at Dartmouth.
Having created what he considered a perfect structure at the military academy, Thayer resisted all subsequent attempts at modification, blasting other reformers with his vitriolic pen despite their contributions to the institution. In some respects he succeeded. Key elements of the Thayer system remain in force at West Point today.
