Henry David Thoreau, Canoe Trip -- Poet of Nature, Poets and Poetry at Aspirennies.com

Henry David Thoreau was born in 1817 in Concord, Mass. Though his family moved the next year, they returned in 1823, not to move again. Even when he grew ambivalent about the village after reaching manhood, it remained his world, for he never grew ambivalent about its lovely setting of woodlands, streams, and meadows. Little distinguished his family. He was the third child of a feckless small businessman named John Thoreau and his bustling, talkative wife, Cynthia Dunbar Thoreau. His parents sent him in 1828 to Concord Academy. There he impressed his teachers and so was permitted to prepare for college. Upon graduating from the academy, he entered Harvard in 1833. At Harvard he was a good student, but he was indifferent to the rank system and preferred to use the school library for his own purposes. Graduating in the middle ranks of the class of 1837, he searched for a teaching job and secured one in Concord at his old grammar school. But he was no disciplinarian, and he resigned after two shaky weeks, after which he worked for his father in the family pencil-making business. In June 1838 he started a small school with the help of his brother John. Despite its progressive nature, it lasted for three years, until John fell ill.

A canoe trip that he and John took along the Concord and Merrimack rivers in 1839 confirmed him in the opinion that he ought to be not a schoolmaster but a poet of nature. As the 1840s opened, he took up the profession of poet. Henry David Thoreau struggled to stay in it and succeeded throughout the decade, only to falter in the 1850s. --Encyclopedia Britannica
