He was admitted to Harvard College

Private school student Oliver Wendell Holmes later received admission to Harvard Law University, which is now known as Harvard University. Oliver Wendell Holmes' career as a poet began after he earned his degree in 1861. He started going to Harvard Law School in 1864, and he graduated in 1866. He had initially intended to go to medical school, despite his father's opposition. After passing the bar exam in 1867, he started practicing law right away.

He authored philosophical essays when a student at Harvard and requested that Emerson read his critique of Plato's idealistic philosophy. If you assault a monarch, you must kill him, Emerson retorted. He backed the abolitionist movement, which was extremely popular in Boston society in the 1850s. He belonged to Hasty Pudding and the Porcellian Club at Harvard; both societies also included his father. He serves as both the Secretary and the Poet in Pudding, in addition to being the father. After President Abraham Lincoln called for volunteers following the shooting at Fort Sumter in the spring of that year, Holmes, a Harvard Phi Beta Kappa graduate, joined the Massachusetts militia. However, for a brief period, he returned to Harvard to take part in warm-up exercises.
