Portrait photograph from a ninth-plate daguerreotype of Henry David Thoreau, June 18,1856. "Calvin R. Greene was a Thoreau “disciple” who lived in Rochester, Michigan, and who first began corresponding with Thoreau in January 1856. When Greene asked for a photographic image of the author, Thoreau initially replied: “You may rely on it that you have the best of me in my books, and that I am not worth seeing personally – the stuttering, blundering, clodhopper that I am.” Yet Greene repeated his request and sent money for the sitting. Thoreau must have kept this commitment to his fan in the back of his mind for the next several months. On June 18, 1856, during a trip to Worcester, Massachusetts, Henry Thoreau visited the Daguerrean Palace of Benjamin D. Maxham at 16 Harrington Corner and had three daguerreotypes taken for fifty cents each. He gave two of the prints to his Worcester friends and hosts, H.G.O. Blake and Theophilius Brown. The third he sent to Calvin Greene in Michigan. “While in Worcester this week I obtained the accompanying daguerreotype – which my friends think is pretty good – though better looking than I,” Thoreau wrote.
