The 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. Edison dictated his answers to an assistant who handwrote his replies in a hand resembling Edison's.

The Nobel Prize winning physicist apologizes for a missed appointment due to having been in his lab. Rare ALS: "P. Curie", 1½p, 5¾x4¼, front and verso. Faculté des Sciences de Paris, Cours de Physique, Paris, 1904 May 29. To an unnamed woman. Written from the Curie home at 108 Boulevard Kellerman. In French, translated. In full: "We sincerely regret Mme Curie and I having missed your appointment yesterday, which you granted us. I was in the laboratory yesterday at 5:30 in the evening. I found your letter but it was already too late and Mme Curie does not go to the laboratory at this time. Please excuse us and accept our sincerest best wishes." Five months earlier, Pierre and Marie Curie shared the 1903 Nobel Prize in Physics with Antoine Henri Becquerel for discovering radioactivity and studying uranium. The Curies continued their work on radioactivity, but Marie did not go to the laboratory as often as before. She was then three months pregnant and radioactive material was not something of which to be in contact. The Nobel Prize brought the Curies overwhelming public popularity, to their dislike. The volume of visitors made it impossible for them to work with the reclusiveness they so much enjoyed.

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.

Rare manuscript letter written from his estate in England to Inslee Hopper, his successor as head of the Singer Manufacturing Co. in New York. Hopper has added his receipt acknowledgement in purple ink! Manuscript Letter signed: "I M Singer", 1p, 5x8. Paignion, South Devon, England, 1873 July 8. To The Director of the Singer Manufacturing Co., New York. In full: "On receipt of this letter, please send me sight Bill of Exchange for Five thousand pounds (£5000) but should Gold and Exchange exceed 125 you may wait until you are able to buy at that price. I have telegraphed to Mr. Hawley to come out, and write to you as I expect he will sail before this letter arrives." Ink note receipt acknowledgement by Singer President Inslee Hopper: "July 23 73". Singer received his first patent for a commercial sewing machine in 1851. Three years later, he introduced a domestic model that made him one of the wealthiest Americans of the century. In late 1857, Singer opened the world's first mass production facility for something other than firearms in New York. I.M. Singer & Company was soon able to cut production costs to a little more than $10.00 per machine. Singer sold his new machines for 50% less than his first, yet had increased his profit margin to 530% per machine.

The chemist penned and signed this note asking Mr. Potterin to speak to him later Autograph Note signed: "L.P.", in black ink. One page. 2¾x1¼. To "Mr. Potterin - Eugene". In French, translated in full: "Speak to me about him after/the arrival of Mr. Lapetair, the injector, etc." Louis Pasteur (1822-1895) was a chemist and biologist who is considered one of a handful of the most important pioneers of microbiology. His body of work directly led to the development of vaccinations to protect humans from deadly diseases, the invalidation of the spontaneous generation theory of life, and the invention of pasteurization. Pasteurization is the process of heating dairy products to eliminate microbial organisms that can spread disease. Germ theory was already rapidly growing support, but Pasteur conducted controlled experiments from 1860-1864 that investigated germs, disease, and potential causality. These experiments put to rest any further serious opposition to the theory. While Pasteur's influence on microbiology and chemistry stretch far into the sciences, his notoriety today is primarily due to the namesake process of pasteurization used on virtually all dairy products sold in stores.

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). Minor surface blemishes at blank margins. Fine condition. Frame has minor surface ships and wearing at corners.

He signs a glowing (1854) autograph letter, enthusiastically recommending his former assistant Otis Wood to any prospective employer. 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.…"
