The Daugherty Visible typewriter was invented by James Daugherty. It was produced ca.1891 by The Daugherty Typewriter Company of Kittanning, Pennsylvania. The Daugherty is often cited as being the first commercially successful frontsrike, four-row typewriter to produced. Unfortunately, there was an incident at the factory that halted production of the Daugherty. Another frontsrike, four-row typewriter then took its place, the Underwood Standard, and the rest is history. Some Daugherty typewriters were rebranded as the American or Americo.
