Typewriter

It's a machine that prints letters, numbers and other signs when their keys are pressed.

The typewriter was patented as mechanic help for the blind. It`s was recorded in the United States in 1829 by Guillermo A. Burt and was called typography but no model survived.

The first practic typewriter and that could make in large scale was created by three american inventors: Cristobal I. Sholes, Samuel W. Soule and Carlos Glidden.

I think this invention is very important because it was a great ancestor of the computer and in spite of technology we have today and we still use in different areas.
