The child of a distinguished Boston family, Richard Henry Dana Jr. (born 1815) dropped out of Harvard to try his hand at sea-faring. He sailed out of Boston on a merchantman, headed around the Horn to California (which was part of Mexico at the time).
The result was his classic Two Years Before the Mast. It is written in a journalistic style. He went on to a career as a lawyer and in politics.
As a friend of Herman Melville, who read his book, Dana suggested that Melville do a similar sort of book, but about whaling. Melville did.
