Henry David Thoreau

Henry David Thoreau (b. 1817–d. 1862) is best known as the author of Walden (1854), a pivotal work in American nature writing, and “Civil Disobedience” (1849), an influential call to resist war and slavery. Soon after graduating from Harvard College in 1836, Thoreau was befriended by Ralph Waldo Emerson, whose Nature (1836) depicted the natural world as a book of spiritual and ethical wisdom. Emerson encouraged Thoreau’s writing and journal keeping, and provided space on his property near Walden Pond for a writing retreat. The book that Thoreau wrote there, A Week on the Concord and Merrimack Rivers (1849), was a disappointing commercial failure. However, Thoreau’s effort to explain his experiment in solitude to his Concord neighbors yielded Walden, a literary masterpiece. Walden presented not only a moving description of a life close to nature as the seasons move through the year, but also a scalding critique of social institutions, conventional politics, and the deadness of conformist life. The writing of Walden, completed after Thoreau’s 1847 return to Concord, was an extended process in which Thoreau worked through seven drafts. Midway through the composition, in the early 1850s, Thoreau underwent an intellectual reorientation that can be described as a conversion from poet-philosopher to naturalist-scientist. He devoted effort to his Journal as a record of nature observation during his daily hikes. The gathering and organization of the particular facts of natural history gradually became his principal task until his death in 1862. His developing naturalist sensibility is evident in essays such as “Walking,” “Wild Apples,” and “Autumnal Tints.” These works retained his descriptive craft and vital prose style, and demonstrated his observational practice in the natural world. These essays were published in the early 1860s, but other projects such as Wild Fruits and his seasonal “Kalendar” of Concord remained unfinished. These and other works have been brought to life by recent research and scholarly editing of his surviving manuscripts. The recent discovery that Thoreau’s seasonal records could serve as a source for the scientific measurement of climate change has brought a new attention to the value of his later natural history investigations, showing him as a naturalist fully in step with the developments of 19th-century science. Thoreau’s antislavery fervor increased as the Civil War approached, and he followed the publication of “Civil Disobedience” with political essays characterized by an ardent condemnation of slavery and an impassioned defense of abolitionist John Brown.
