Henry David Thoreau was an American essayist, journal‐keeper, naturalist, and abolitionist who wrote on subjects ranging from the self, society, slavery, and the state to wilderness, walking, and wild apples. Thoreau was born, lived, and died – at an early age from tuberculosis – in Concord, Massachusetts and rarely left his hometown except for brief trips in New England, and to New York, Minnesota, and Canada. He is typically classified with Ralph Waldo Emerson as a significant thinker in the American transcendentalist school of thought and as an American Renaissance writer alongside Nathaniel Hawthorne, Edgar Allen Poe, Emily Dickinson, Herman Melville, and Walt Whitman. During his own life, Thoreau was often overshadowed by Emerson and his writings proved difficult to publish and only achieved very minimal market success. But his importance as a key American thinker has grown continually since his death and today he is well known for both his “reform writings” and his “nature writings.”
