SAMUEL F.B. MORSE One year before his first successful telegraph message, Morse signs an autograph letter to Treasury Secretary John Spencer, explaining that the cost of preparing the wire will be $10 more than his previous estimate. He'll still come in under budget! ALS: "Saml F.B. Morse", 1 page, 8x10. New York, 1843 May 1. To Secretary of the Treasury John C. Spencer. In full: "In my letter of the 29th ulto accompanying the contracts for the Telegraphic Wire, and the expenses of covering, I left a blank in the former which I observed was to be filled with a sum not exceeding 24 cents pr.lb. I have this moment heard from Paterson, and am enabled to fill the said blank with 22 cents. This varies the expense of Preparation of the Wire as given in my letter to the Department of 26th ulto from $1900 to $1910 - making the contracts for this part of the work of $690 less than the original estimates, instead of $700 - as therein stated." Samuel Finley Breese Morse (1791-1872), a portrait painter and a founder and first President of the National Academy of Design (1826-1845, 1861), interested himself in the possibilities of a magnetic telegraph in 1832. He developed the Morse Code for use in the telegraph instrument. read more...
