Henry David Thoreau
Henry Thoreau was born in Concord, Massachusetts, in 1817, and attended Concord Academy and Harvard. After a short time spent as a teacher, he worked as a surveyor and a handyman, sometimes employed by Ralph Waldo Emerson. Between 1845 and 1847 Thoreau lived in a house he had made himself on Emerson's property near to Walden Pond. During this period he completed A Week on the Concord and Merrimack Rivers and wrote the first draft of Walden, the book that is generally judged to be his masterpiece. He died of tuberculosis in 1862, and much of his writing was published posthumously.
