Graeme Monroe Hammond (February 1, 1858 – October 30, 1944) was an American neurologist and sportsman who advocated for physical exercise as treatment for nervous disorders.

Graeme Hammond later recalled his regular trips as a young boy, accompanying Abraham Lincoln to visit wounded soldiers during the war.

[6] During his entire professional career, Hammond was a professor of nervous and mental diseases at NYU School of Medicine,[7] serving as the chair in neurology from 1898 to 1920.

"[8] Hammond was a lifelong advocate of regular physical exercise as a prevention and cure for most diseases, including nervous and mental disorders.

[9] According to the Harvard Gay & Lesbian Review, Hammond thought that homosexuality was caused by "nervous exhaustion and that bicycle exercise would restore health and heterosexuality.

"If women were forced to enjoy the rigorous training entailed by life in a fighting army, this overindulgence would of course be summarily stopped.

He won multiple championships in fencing and was the United States champion for foil (1891), épée (1889, 1891, 1893) and sabre (1893, 1894).

"[16] Hammond, who both smoked and drank daily, advocated consistent and proper exercise as the key to good health.
