Thoreau, Henry David

Thoreau, Henry David thôr´ō, thərō´ [key], 1817–62, American author, naturalist, social activist, and philosopher, b. Concord, Mass., grad. Harvard, 1837. Thoreau is considered one of the most influential figures in American thought and literature. A supreme individualist, he championed the human spirit against materialism and social conformity. His most famous book, Walden (1854), is an eloquent account of his experiment in near-solitary living in close harmony with nature; it is also an expression of his transcendentalist philosophy (see transcendentalism).

Thoreau grew up in Concord and attended Harvard, where he was known as a serious though unconventional scholar. During his Harvard years he was exposed to the writings of Ralph Waldo Emerson, who later became his chief mentor and friend. After graduation, Thoreau worked for a time in his father's pencil shop and taught at a grammar school, but in 1841 he was invited to live in the Emerson household, where he remained intermittently until 1843. Becoming an important part of the Concord community, he served as handyman and assistant to Emerson, helping to edit The Dial and contributing poetry and prose to the transcendentalist periodical.

In 1845 Thoreau built himself a small cabin on the shore of Walden Pond, near Concord; there he remained for more than two years, living deep and sucking out all the marrow of life. Wishing to lead a life free of materialistic pursuits, he supported himself by growing vegetables and by surveying and doing odd jobs in the nearby village, but he devoted most of his time to observing nature, reading, and writing. He kept a detailed journal of his observations, activities, and thoughts, and from it he distilled his masterpiece, Walden. The journal, begun in 1837, was also the source of his first book, A Week on the Concord and Merrimack Rivers (1849), as well as of his posthumously published Excursions (1863), The Maine Woods (1864), Cape Cod (1865), and A Yankee in Canada (1866).

One of Thoreau's most important works, the essay Civil Disobedience (1849), grew out of an overnight stay in prison as a result of his conscientious refusal to pay a poll tax that supported the Mexican War, which to Thoreau represented an effort to extend slavery. Thoreau's advocacy of civil disobedience as a means for the individual to protest those actions of his government that he considers unjust has had a wide-ranging impact—on the British Labour movement, on the passive resistance independence movement led by Mohandas Gandhi in India, and on the nonviolent civil-rights movement led by Martin Luther King, Jr., in the United States. After he left the Walden cabin, Thoreau and his family took an active part in the abolitionist movement.

Thoreau is also significant as a naturalist who emphasized the dynamic ecology of the natural world, helping to lay the foundations for environmentalism, and was an early advocate for the creation of national parks. Above all, Thoreau's quiet, one-man revolution in living at Walden has become a symbol of the willed integrity of human beings, their inner freedom, and their ability to build their own lives. Thoreau's writings, including his journals, were published in 20 volumes in 1906. He wrote many volumes of notes on the Native Americans of the NE United States, as well as careful studies of flowering plants and of trees in burned and logged forests.
