Major John Buttrick (July 20, 1731 May 16, 1791, Concord, Massachusetts) was one of the leaders of the Concord militia during the Battle of Concord on April 19, 1775. Given the usual interpretation of the first stanza of Ralph Waldo Emerson's famous poem "Concord Hymn," Buttrick is the man who ordered "the shot heard around the world."
