- Letter from Alfred Vail, assistant to Samuel F. B. Morse, inventor of the first telegraph, to Joseph Henry, then a professor at Princeton University and later first Secretary of the Smithsonian Institution, July 17, 1846. In the letter, Vail apologizes for offending Henry by not crediting Henry's work in electromagnetism in Vail's publication on Morse's telegraph. Though Morse was credited with having invented the first telegraph, Henry asserted that Dr. Leonard Gale, who advised Morse on his first model of an electromagnetic telegraph, was able to correct imperfections in the model because of his knowledge of Henry's principles.
