Henry David Thoreau (1817–1862) was an American essayist, naturalist, philosopher, and poet. Born at Concord, Massachusetts, and educated at Harvard, he began his career as a teacher. Through his older friend and neighbor, Ralph Waldo Emerson, he became a part of the Transcendentalist circle and one of that group’s most eloquent spokespersons. He is best known for his book, Walden, and his essay, “On the Duty of Civil Disobedience.”
