(1817-1862) went to Harvard, but did not like the conformity (or better said, unity) of the college. During 1838 - 1841, Thoreau became friends with Ralph Waldo Emerson. In 1844, Thoreau, with Emerson's permission, built on land that Emerson owned, called Walden Pond. He lived there for 2 years and this is what inspired his work Walden. While he was at Walden he was arrested fro not paying his poll tax and thrown in jail (though he was bailed out by Emerson the next day). This jail experience led to the wirting of Civil Disobedience, the essay that inspired Ghandi, which inspired Martin Luther King Jr.
