SAMUEL F.B. MORSE He signs a glowing (1854) autograph letter, enthusiastically recommending his former assistant Otis Wood to any prospective employer. Framed in a Gallery of History display to 36x22 ALS: "Sam. F.B. Morse," 1½ pages, 7½x9¾. Po'keepsie, 1854 February 3.To Otis E. Wood, Esq., Utica.In full: "Most happy shall I be, if by a simple letter of mine, I can render you or your worthy brothers any service. Your brother Orrin S. Wood was my first Telegraph pupil, after the first (the experimental) line was established between Washington & Baltimore. He will undoubtedly recollect my predictions at that time, for him, that having taken the enterprize at its very commencement, and made himself thus early master of all that pertained to it, he would have an experience, possessed by no other, which would enable him to command any position he might choose, not only one of usefulness but I believed also of fortune. I am gratified in believing that he has attained a position, at least of well earned competence if not of fortune, which he richly deserves for his high and honorable personal character, as well as his eminent Skill & perseverance.

THOMAS A. EDISON.Partly printed historic Manuscript DS: "T.A. Edison," and on a 5-cent Revenue Stamp bearing George Washington's likeness "TAE/Jan 17/1872", 1p, 8½x14. New York, 1872 January 17.The 24-year-old inventor sells the rights to his invention of an improvement in District and Alarm Telegraphs. Edison had been a telegraph operator. At the time of this document, Edison was immersed in devising inventions for the use and improvement of the telegraph. He had also been involved in the improvement of the stock ticker. With the $40,000 he gained from selling some of his stock ticker inventions he was able to establish his Newark, NJ laboratory. His years at Newark (1870-1876) were characterized by a number of telegraph patents and partnerships. The year of this document marked the start of a four-year period during which Edison conducted the manufacturing of telegraphic instruments for Western Union Telegraphic Co. and the Automatic Telegraph Co. He had several workshops in Newark. He worked on and completed the motograph, automatic telegraph system, duplex, quadruplex , sextuplex and multiplex telegraph systems.

SAMUEL F.B. MORSE His signed, handwritten letter to telegraphic expert Robert Sabine (1868), insisting that he be given journal space to refute "Hamel's calumnious paper read before the Society of Arts". ALS: "Saml F.B. Morse, 3 pages, 5x8. Po'keepsie, N.York,1868 August 8. The inventor of the Morse Code who established a telegraph line between Washington, D.C., and Baltimore in 1844 writes to Robert Sabine, Westminster, London. In full: "I began a letter to you on the 18th July in reply to your valuable letter of the 18th of June. I have had so many interruptions since my return that I must defer its completion, until I have finished by Report as Commissioner for my Government. I write now simply to acknowledge your kindness and to thank you for your courtesy, and to promise you at no very distant day the finished letter on Hamel's calumnious paper read before the Society of Arts. The part in which he refers to me, requires a thorough exposure. I do not ask to have it published entire, but I do ask that it be read to the Society, and that it be recorded in their proceedings, with such remarks of their own as their sense of justice may prompt after a proper examination of the case

Letterhead from Knollwood, Saranac Lake, New York. Dated August 1, 1940. Sent to Dr. Alvin Johnson. In Full: "Mr. Hermann Broch has informed me that I may be asked about Professor Karl Feldmann of Leyden(Holland). My knowledge of Professor Feldmann's work, however, is not sufficient to give a valuation of it. I should be grateful if some papers by him would be sent to me. / With the expression of my highest appreciation of your admirable activities". Framed with two plaques and a 7x9 color reprinted painting by Rick Parks to a total size of 34x20. Albert Einstein (1879-1955) was born in Ulm, Germany. When he was a teenager, his family moved throughout Europe due to his father's work. At various times in his life, he held citizenship from Switzerland, the Weimar Republic, and the United States. Most of his ground-breaking work in physics came well before WWII in the form of his special theory of relativity and his studies in the general theory of relativity.

THOMAS A. EDISONThe famous inventor penned a section of answers on this questionnaire! Printed Questionnaire filled out by an assistant who has signed: "Thomas A. Edison" at the conclusion, but with 11 words in Edison's hand, 1p, 7¾x10½. J.K. Macomber, Professor of Physics at the Physical Laboratory Agricultural College in Ames, Iowa, sent Edison and other authorities in the field, a printed questionnaire, dated September 27, 1879. Macomber message, in part: "The people of the Western States have been imposed upon by lightning-rod peddlers more, perhaps, than by any other class of swindlers. Among other rods being sold in Iowa is one known as the 'Chambers' rod, widely has been patented by the 'Chambers' National Lightning Protection Company,' of Cincinnati, Ohio. Briefly, this system consists on an Iron rod running along the ridge of the building with points at each end projecting upward…Many public buildings in thus State have been furnished with these rods…I beg leave to submit the following interrogations." Macomber lists seven questions for Edison to answer.

SAMUEL F.B. MORSE One year before he sent his first telegraph message, Morse signs an autograph letter to Treasury Secretary Spencer, requesting $600 to cover the cost of his lab and office. Important ALS: "Saml F.B. Morse", 1 page, 8x10. New York, 1843 May 18. To Secretary of the Treasury John C. Spencer, who has penned: "Approved/J.C.S." on verso of the integral sheet.

The law provided the money "for testing the capacity and usefulness of the system of electro-magnetic telegraphs invented by Samuel F.B. Morse of New York" so any other funds, such as rent for his laboratory and office, had to be applied for by Morse.

SAMUEL F.B. MORSE and SARAH E. MORSE The two sign a 3-page, handwritten 1863 letter to their son Willy, away at school Autograph letter signed: "Yr Affectionate Father/Saml F.B.

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.
