After graduating from Harvard, Lincoln enrolled at Harvard Law School. When he initially expressed interest in the law school to his father, President Lincoln made reference to his own pleasant, but informal legal training by stating "If you do, you should learn more than I ever did, but you will never have so good a time." Robert Lincoln attended Harvard Law School from September 1864 to January 1865, and left in order to join the Union Army. In 1893, Harvard awarded Lincoln the honorary degree of LL.D.
