Henry David Thoreau moved to Concord, Massachusetts around the same time that the Alcott family did (in 1845). Like the Alcotts, Thoreau had a distinctive philosophy; his involved the conservation of natural places. This handsomely illustrated and informally told glimpse at a particular activity is based on Thoreau’s work to prevent a factory being built in Concord. (Walden Pond (opens in a new window) is now a state park.)
