Excellent question... you actually made me look for the answer in Wikipedia. \n\n"In 1891, Karl Elsener, then owner of a company that made surgical equipment discovered (to his dismay) that the pocket knives supplied to the Swiss Army were in fact made in Germany. Outraged, he founded the Association of Swiss Master Cutlers. Its goal was simple: Swiss knives for the Swiss Army.\n\nElsener began working on what was the predecessor to the modern Swiss Army knife, called the "Soldier's Knife". The original had a wooden handle (as opposed to the plastic and metal seen today), and featured a blade, a screwdriver, a can opener, and a punch. This knife was sold to the Swiss army, but Elsener was not satisfied with its first incarnation. In 1896, after 5 years of hard work, Elsener managed to put blades on both sides of the handle using a special spring mechanism, allowing him to use the same spring to hold them in place, an innovation at the time. This allowed Elsener to put twice as many features on the knife; he added a second blade and a corkscrew."\n\nInteresting. It appear that Elsener, through his company Victorinox, was indeed the inventor of the Swiss Army Knife.

Thomas Alva Edison (February 11, 1847 – October 18, 1931) was an American inventor and businessman who developed many devices which greatly influenced life in the 20th century. Dubbed "The Wizard of Menlo Park" by a newspaper reporter, he was one of the first inventors to apply the principles of mass production to the process of invention, and can therefore be credited with the creation of the first industrial research laboratory. Some of the inventions credited to him were not completely original, but alterations of earlier patents (most famously the light bulb), or were actually the work of his numerous employees. Nevertheless, Edison is considered one of the most prolific inventors in history, holding 1,093 U.S. patents in his name, as well as many patents in the United Kingdom, France, and Germany.

Blaise Pascal? He invented the calculator. Maybe Isaac Newton, the inventor of calculus, or Charles Babbage, the inventor of the computer. Perhaps John Napier, who discovered how to add, subtract, multiply, divide, and even extract square roots simply by moving pieces on a chessboard? Tell you what, pick René Descartes, he's the inventor of coordinate geometry. These are all excellent choices!

Last Sunday I sharpened a pencil but there wasn't any batteries in the thing so I just manually twisted my pencil around in it.  As for the type in your picture, I haven't used one of those since I was in school back in 1983.

Walker is noted as being the first Black woman millionaire in this country who made millions in the early 1900's introducing a "straightening comb", and promoting other Black hair care products that allowed Black women to get the "kinks" out of their hair.
