In 1873 Christopher Latham Sholes designed, and the Remington Arms Company put on the market, the first workable typewriter. ... The keyboard arrangement of Sholes' 1873 typewriter was typically the product of its time. ... Sholes' primary problems were mechanical. The action of his machine was so sluggish that to avoid the clashing of typebars being struck in succession he purposely sought to locate in different quadrants of the typebar circle the letters most frequently used together in words. -- August Dvorak: "There Is a Better Typewriter Keyboard", National Business Education Quarterly, Vol.12, No.2 (December 1943), pp.51-58,66.
If Dr. Dvorak was true, the keyboard arrangement of Sholes' 1873 typewriter should be totally different from the one of Sholes' 1872 typewriter. Since the 1873 commercial model (U. S. Patent No.207559) was different from the 1872 trial model (U. S. Patent No.182511) in its mechanism to connect keys with typebars. However, in fact, the keyboard arrangement of the 1872 model (shown right, taken from "The Type Writer", Scientific American, Vol.27, No.6 (August 10, 1872), p.79) were very similar to QWERTY of the 1873 model. Furthermore, in the 1873 model, the letters E and R were in the same quadrant of the typebar circle (cf. Richard E. Dickerson: "Did Sholes and Densmore Know What They Were Doing When They Designed Their Keyboard?", ETCetera, No.6 (February 1989), pp.6-9), though "er" and "re" are very frequently used in English words. Here we conclude that Dr. Dvorak's hypothesis, in which he insisted that QWERTY was intended to avoid the clashing of typebars, is false.
Additionally, Remington Arms Company was formed in 1888, and it has had nothing to do with typewriter business. In 1873 the company name was E. Remington & Sons. In 1886 E. Remington & Sons sold its typewriter division to Wyckoff Seamans & Benedict, then the division was named Remington Standard Typewriter Manufacturing Company. The company was renamed Remington Typewriter Company, Remington Rand, Sperry Rand, and now Unisys.
