Soule, Carlos Glidden and John Pratt, has been contended to be one of the inventors of the first typewriter in the United States. [3] [4] [5] He was also a newspaper publisher and Wisconsin ...

Initially, the keyboard of an instrument such as a pipe organ or harpsichord could only produce sounds of one particular volume. In the 18th century, the pianoforte was invented. The pianoforte had metal strings which ...
The first prototype of a computer mouse, as designed by Bill English from Engelbart's sketches [1]. Early dynamic information devices such as radar displays, where input devices were used for direct control of computer-created data, set the basis for later improvements of graphical interfaces. [2]

These were soon replaced with a ball-type mouse, which was invented by Ronald E. Rider and developed by Bill English. These are photo-mechanical mice, first using white light, and then infrared (IR), to count the rotations of wheels inside the mouse. Each key on the Alto keyboard is represented as a separate bit in a set of memory locations.
