Frederic Heath, Milwaukee, spoke on " The Typewriter in Wisconsin."
The first typewriter, cumbersome and box-like with both
white and black keys like a piano, was invented in 1868 by
Christopher Latham Sholes in Charles Kleinsteuber's machine
shop at 322 West State Street, Milwaukee, which is now the Stag
Hotel.

In a series of letters, 1869-89, written to his partners, James and
Amos Densmore, Christopher Latham Sholes describes minutely his
hopes and disappointments over his " writing machine." Sholes's typewriter
was patented in 1868, but he spent the remainder of his life
improving and perfecting it. The original letters, all written on the
typewriter, are the property of Mr. Clint Densmore of Marquette,
Michigan, and have been copied by the Society through the courtesy
of his daughter, Miss Priscilla Densmore.
