WAHL, John Conrades, inventor and'
manufacturer, b. near Morrisonville, Illinois,
7 February, 1876. He learned the trade of a
machinist, and worked at it in Peoria, Illinois,
after 1897. In the meantime, he pursued an.
extensive course
in draughtsmanship, which lie
completed in 1902,
and was then engaged as a tool
designer by th e
Universal Adding
in St. Louis, M issouri. In 1903 he
designed one of I
the earliest visible
typewriting machines, and in 1904
he perfected the
famous Wahl adding and subtracttin g attachments
for the Remington Type w riter In 1905
the Wahl Adding Machine Company was incorporated, and a plant erected in Chicago
for the manufacture of the adding and subtracting machine. In 1907 a contract was negotiatedl with the Remington Typewriter Company which covered a period of eighteen years.
Thirteen years later (1920) this attachment
had become such a necessary adjunct to the
Remington machine that the Remington Company bought outright from the Wahl Adding
Machine Company, all its machinery, equipment, and patents. In 1915 Mr. Wahl perfected the "Eversharp" pencil, which has since
become famous. This and the Wahl Fountain
Pen are manufactured and marketed by the
Wahl Company, of which he is first vice-presi(lent. In recent years Mr. Wahl has directed
his inventive genius toward effecting improvements in the design of writing implements and
equipment for their manufacture. He has been
granted over fifty patents for various inventions. Among the important awards of merit
received by Mr. Wahl may be mentioned the
industrial medal of the Panama-Pacific Exposition (1915), and the John Scott Legacy's
medal and premium of the Franklin Institute,
Philadelphia (1915). Mr. Wahl married, in
1897, June Estabrook. They have one child,
