Garrit Terhune, physician, was born in 1801 in New Barbados Township, New Jersey, son of Richard and Hannah Terhune. He studied medicine at the College of Physicians and Surgeons (now the Vagelos College of Physicians and Surgeons, Columbia University) during the 1825-1826 academic year. Due to a dispute over governance and salaries most of the faculty seceded from the College at the end of that school year and formed a new medical school under the auspices of Rutgers College. Terhune followed them to Rutgers from which he received his medical degree in 1827.
After practicing two years in Hackensack, New Jersey, Terhune moved to Acquackanonk Village (now Passaic, New Jersey) in 1829. He remained there for the rest of his life. He was one of the founders of the Passaic County Medical Society and at his death on July 2, 1885, he was the oldest physician in the county.
