CHARLES BABBAGE - AUTOGRAPH NOTE SIGNED 5/23 - HFSID: 350482

The famed mathematician sends a dinner invitation. Third Person ANS: "Mr. Babbage", 1p, 3½ x 3¾. Dorset St., (no year) May 23. In full: "Mr. Babbage will have the honor of dining with Mr & Mrs Strutt on Saturday the 11th June". 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. Framed to an overall size of 27½ x 16¼. Frame exhibits wearing at corners.

Sigmund Freud signed this typed letter to his nephew, publicist Edward L. Bernays, in 1924 on his personalized stationery. In it, Freud discusses family finances and thanks Bernays for a case of coffee. Typed letter signed "Sigm". Pencil marks on page 2 in unknown hand. 2 pages, 5¾x8¾, 1 sheet, front and verso, on Freud's personalized stationery. May 11, 1924. In German, translated. In part: "Also in May, I lent you 150 dollars, so that your mother's assets with me are now 460 dollars. Thus, three further months are paid for. I would suggest that you send a larger amount of money here after these three months... The case of Washington Coffee arrived undamaged on 30 IV. I very much approve of you deducting the price for that upcoming royalties. I didn't expect the coffee to be so expensive, however, I received your book from Boni & Liveright. As a real American, I was very interested in it...". We believe that this letter was written to Edward Bernays, Freud's nephew, as it mentions sending money to an "Onkel [Uncle] Alexander". EDWARD L. 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.

TLS: "R.J. Gatling", 1p, 8½x11½. Hartford, Conn., 1885 April 14. As President, on stationery of The Gatling Gun Company. To Colt's Patent Fire Arms Manufacturing Company, Hartford. In full: "The Chief of Ordnance, State of New York, advises us that he has sent two Gatling Guns here for repairs, and that if anything is needed in the way of appendages or spare parts, that he be furnished with a list of the same, before he gives the order for them.

ENZO FERRARI - PAMPHLET SIGNED - HFSID: 350506

The framed race car engineer signs a biographical page from a pamphlet. Pamphlet signed: "Ferrari", 8 x 11¼. Enzo Ferrari (1898-1988), whose name is synonymous with quality engineering, began his racing career in 1919 and soon became a test driver for Alfa Romeo. About 1939, Ferrari organized his own factory but was prevented from producing his own automobiles for four years because of a contract with Romeo, which feared competing against the famed Ferrari name. During WWII, Ferrari's factory was converted to produce ball bearings and other equipment. In 1947, however, Ferrari's first car with the prancing horse insignia debuted. A lifetime racing enthusiast, Ferrari produced few automobiles for private consumer sales until the 1953 debut of the 250 Europa, the first of the long line of Ferrari street cars that to this day remain highly valued as collectibles. Ferraris excelled on international racing circuits and garnered ten wins in the Formula One Constructors' Championship from 1956 to 1983 - more than any other make. Surface creases, otherwise fine condition. Framed to an overall size of 15 x 25¾. 8 photocopied pages of the pamphlet included on back of frame.

WERNHER VON BRAUN - AUTOGRAPH MANUSCRIPT SIGNED - HFSID: 350447

The man who pioneered the concept of the space shuttle writes about space travel. Autograph Manuscript signed: "By Dr. Wernher von Braun" in title, 1p, 8¼ x 10½ ruled sheet. Manuscript page, which is written in pencil, is part of a longer manuscript ("1" written by von Braun at upper margin). Headed: "Space Travel/by Dr. Wernher von Braun/Chief, Guided Missile Development Division//Redstone Arsenal, Huntsville, Ala." In full: "There are few dreams of the future which have woven so fascinating a web around human fantasy as flight through space. Since the first, epoch-making experiments of the great American pioneer of rocketry, Robert H. Goddard; since the days when Hermann Oberth, the German, and the Russian Constantin E. Ziolkovsky published their startling writings on rocket propulsion, a veritable spate of literature has overwhelmed the public. This has covered the entire field ranging from serious, scientific dissertations to comic strips. Thus, the intelligent layman outsider who is at tempting to sift the actual promises of space flight from idle conjecture frequently finds himself more confused than before he began to [word crossed out] study space flight literature.…"

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.…"

HENRY FORD - AUTOGRAPHED SIGNED PHOTOGRAPH CO-SIGNED BY: HARRY G. - HFSID 350483

Extraordinary photograph capturing the two innovators together. Rare Photograph signed: "Henry Ford" and "Harry Ferguson". Sepia, 13¾ x 11 overall, image 11 x 8 (one surface). HARRY FERGUSON, a manufacturer of tractors in England and Ireland, developed the Ferguson tractor, a scale model of which is shown on the table in this photograph. His system of tractor-implement integration utilized a hitch, the linkages, and controls of which made the tractor and implement work as a single unit operated almost entirely from the seat of the tractor. Seeking an American market for his product, Ferguson entered into an agreement with HENRY FORD and the Ford Motor Company. Ford, who had formed Ford Motor Company in 1903 and was noted for introducing the successful assembly-line method of production, was to manufacture and market the Ferguson tractor in the U.S. The company commenced making the tractors in 1938, but the agreement was terminated after WWII. Ferguson then began manufacturing his own equipment in Great Britain and the U.S. Portions of 3 middle letters of Ferguson's signature on dark portion (adequate contrast).

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.
