Walden (also known as Life in the Woods) by Henry David Thoreau is one of the best-known non-fiction books written by an American. Published in 1854, it details Thoreau's life for two years and two months in second-growth forest around the shores of Walden Pond, not far from his friends and family in Concord, Massachusetts. Walden was written so that the stay appears to be a year, with expressed seasonal divisions. Thoreau called it an experiment in simple living. Henry David Thoreau (July 12, 1817 – May 6, 1862; born David Henry Thoreau) was an American author, naturalist, transcendentalist, tax resister, development critic, and philosopher who is best known for Walden, a reflection upon simple living in natural surroundings, and his essay, Civil Disobedience, an argument for individual resistance to civil government in moral opposition to an unjust state.
