Best known for his book Walden and his essay Civil Disobedience, Henry David Thoreau was a writer, philosopher, naturalist, and abolitionist, and was closely associated with Concord and Walden Pond in Massachusetts. In 1845, he moved to a small cabin near Walden Pond, where he lived simply for two years while observing nature and reflecting on society. Those experiences became the basis for Walden, a classic work on self-reliance and simple living.
