Youth and political career
Born in Mooresburg, Pennsylvania, Sholes moved to nearby Danville as a teenager, where he worked as an apprentice to a printer. After completing his apprenticeship, Sholes moved to Milwaukee, Wisconsin in 1837. He became a newspaper publisher and politician, serving in the Wisconsin State Senate 1848-1849, 1856-1857, and the Wisconsin State Assembly 1852-1853.[4][5] He was instrumental in getting the death penalty abolished in Wisconsin: his newspaper, The Kenosha Telegraph, reported on the trial of John McCaffary in 1851, and then in 1853 he led the campaign in the Wisconsin State Assembly.[6] He was the younger brother of Charles Sholes (1816-1867) who was a newspaper publisher and politician who served in both houses of the Wisconsin State Legislature and as mayor of Kenosha, Wisconsin.[7]The "Voree plates"
In 1845, Sholes was working as editor of the Southport Telegraph, a small newspaper in Kenosha, Wisconsin. During this time he heard about the alleged discovery of the Voree Record, a set of three minuscule brass plates unearthed by James J. Strang, a would-be successor to the murdered Mormon prophet Joseph Smith, Jr..[8] Strang asserted that this proved that he was a true prophet of God, and he invited the public to call upon him and see the plates for themselves. Sholes accordingly visited Strang, examined his "Voree Record," and wrote an article about their meeting. He indicated that while he could not accept Strang's plates or his prophetic claims, Strang himself seemed to be "honest and earnest" and his disciples were "among the most honest and intelligent men in the neighborhood." As for the "record" itself, Sholes indicated that he was "content to have no opinion about it."[9]Inventing the typewriter
Main article: Sholes and Glidden typewriter
Sholes had moved to Milwaukee and became the editor of a newspaper. Following a strike by compositors at his printing press, he tried building a machine for typesetting, but this was a failure and he quickly abandoned the idea. He arrived at the typewriter through a different route. His initial goal was to create a machine to number pages of a book, tickets, and so on. He began work on this at Kleinsteubers machine shop in Milwaukee, together with a fellow printer Samuel W. Soule, and they patented a numbering machine on November 13, 1866.[10]
Sholes and Soule showed their machine to Carlos Glidden, a lawyer and amateur inventor at the machine shop working on a mechanical plow, who wondered if the machine could not be made to produce letters and words as well. Further inspiration came in July 1867, when Sholes came across a short note in Scientific American[11] describing the "Pterotype", a prototype typewriter that had been invented by John Pratt in England. From the description, Sholes decided that the pterotype was too complex and set out to make his own machine, whose name he got from the article: the typewriting machine, or typewriter.
For this project, Soule was again enlisted, and Glidden joined them as a third partner who provided the funds. The Scientific American article (unillustrated) had figuratively used the phrase "literary piano"; the first model that the trio built had a keyboard literally resembling a piano. It had black keys and white keys, laid out in two rows. It did not contain keys for the numerals 0 or 1 because the letters O and I were deemed sufficient:
3 5 7 9 N O P Q R S T U V W X Y Z 2 4 6 8 . A B C D E F G H I J K L M
At this stage, the Sholes-Glidden-Soule typewriter was only one among dozens of similar inventions. They wrote hundreds of letters on their machine to various people, one of whom was James Densmore of Meadville, Pennsylvania. Densmore foresaw that the typewriter would be highly profitable, and offered to buy a share of the patent, without even having laid eyes on the machine. The trio immediately sold him one-fourth of the patent in return for his paying all their expenses so far. When Densmore eventually examined the machine in March 1867, he declared that it was good for nothing in its current form, and urged them to start improving it. Discouraged, Soule and Glidden left the project, leaving Sholes and Densmore in sole possession of the patent.
Realizing that stenographers would be among the first and most important users of the machine, and therefore best in a position to judge its suitability, they sent experimental versions to a few stenographers. The most important of them was James O. Clephane, of Washington D.C., who tried the instruments as no one else had tried them, subjecting them to such unsparing tests that he destroyed them, one after another, as fast as they could be made and sent to him. His judgments were similarly caustic, causing Sholes to lose his patience and temper. But Densmore insisted that this was exactly what they needed:[14][10]
"This candid fault-finding is just what we need. We had better have it now than after we begin manufacturing. Where Clephane points out a weak lever or rod let us make it strong. Where a spacer or an inker works stiffly, let us make it work smoothly. Then, depend upon Clephane for all the praise we deserve."
Sholes returned to Milwaukee and continued to work on new improvements for the typewriter throughout the 1870s, which included the QWERTY keyboard (1873).[15] James Densmore had suggested splitting up commonly used letter combinations in order to solve a jamming problem caused by the slow method of recovering from a keystroke: weights, not springs, returned all parts to the "rest" position. This concept was later refined by Sholes and the resulting QWERTY layout is still used today on both typewriters and English language computer keyboards, although the jamming problem no longer exists.
Sholes died on February 17, 1890 after battling tuberculosis for nine years, and is buried at Forest Home Cemetery in Milwaukee.
