Who is the author born in 1817 that is associated with a pond from which Frederic Tudor sold ice?
William Tudor:  Another son, Frederic Tudor, founded the Tudor Ice Company and became Boston's "Ice King", shipping ice to the tropics from many local sources of fresh water including Walden Pond, Fresh Pond, and Spy Pond in Arlington, Massachusetts. Walden Pond:  The reservation was designated a National Historic Landmark in 1962 for its association with the writer Henry David Thoreau (1817–62), whose two years living in a cabin on its shore provided the foundation for his most famous work, "Walden; or, Life in the Woods".
