Signed autograph letter (1871) to an experimenter, in which Morse discusses "the present Science of Electro-Magnetism." ALS: "Saml F.B. Morse". 1½ pages, 5 x 8, front and verso. New York, 1871 February 22. The inventor of the Morse Code and the Electromagnetic Telegraph writes to G.W. Varnum, M.D., Montgomery City, Mo. In full: "I received yesterday through my friend & your Cousin J.B. Varnum, Esq your letter of the 16t. instant. In regard to the experiment mentioned in your letter, it is by no means new. Indeed it was from observing this effect, upon a needle, of the magnetism of an electric current (not indeed upon the modern electromagnet, which was the result of his observation,) that Oersted founded the present Science of Electro-magnetism. The use made also of this effect of the magnet upon the needle, to indicate the presence of an electric current upon the telegraph wires, is almost universal in the Offices in Europe; every instrument being furnished with a Galvanometer for the purpose, So although although (sic) not new, you have at least the satisfaction of having independently Suggested a valuable use of the magnetic needle. With respect Yr. Ob. Serv."  G.W.

Charles Babbage (1791-1871) is known as the "Father of Computing" for his ideas about building an analytical engine, the predecessor of the digital computer. He proposed operations research that involved the idea of using machines to perform routine mathematical operations, eliminating errors in human calculation. By 1825, he had developed a machine that was capable of calculating up to 20 decimals. Plans formulated by Babbage in the mid-1830s became the basis for the computers that emerged in the 1940s and 1950s. Lightly stained at upper right blank corner. Fine condition.

Letter in part: "I suppose you are wondering what is becoming of us, and our reduction gears drive motor…This summer we made two different reduction gears, which we tried, but they didn't prove successful, as we couldn't mount them securely enough on the nose of our present crankcase. This forced us to redesign the reduction gear for incorporation on a special crankcase, layout of which is now being completed. If nothing unforeseen happens I expect to have a motor with a new reduction gear running before long". Louis Chevrolet (1878-1941) was born in Switzerland, but moved to France as a boy and then Canada and the United States as a young man.

BERNAYS ()1891-1995, born in Vienna, Austria) was an American publicist and the first publicist to incorporate Sigmund Freud's ideas on psychology into public relations and advertising.

In the summer of 1929, he would also offer lateral cut records and accompanying players, but the company would cease recording operations in October 1929.
