[+] "John Williams Nystrom (Swedish: Johan Vilhelm Nyström) (1825 1885) was a Swedish born, American civil engineer, inventor, and author. He served as an assistant Secretary and Chief Engineer of the United States Navy during the American Civil War.Nystrom received many patents for inventions such as a marine steam engine, a refrigerator, and calculating machines. His slide ruler invention (U. S. patent #7961) was filed with the United States Patent Office on 4 March 1851.Nystrom is most notable for his proposal to switch from decimal to hexadecimal as defined in his 1862 publication titled Project of a New System of Arithmetic, Weight, Measure and Coins, Proposed to be Called the Tonal System, with Sixteen to the Base."[+] Also: In an article of Scientific American the device was hailed as the most important one ever brought before the public. Despite all of the accolades however, it was never widely accepted, and no more than 100 devices were ever produced. This may have been because the cost (there were $10, $15, and $20 models, a huge sum in 1850s), or because the instrument was never well advertised or marketed."--Computer History Museum online (Nystrom). Also see Donald Knuth, The Art of Computer Programming section 4.1 (which is in volume 2).[+].
