The Oliver Typewriter Company was an American typewriter manufacturer headquartered in Chicago, Illinois.   
Their novel mechanism, based on lateral strike, was different than other designs found normally in other typewriters. Oliver Typewriter were considered the first with a “visible print”, meaning the full page is visible to the typist as the text is being entered. Although they were preceded by the Daugherty typewriters, also with “visible print”, Oliver got greater fame due to the intense advertising for household consumption, using local distributors and credit sales. Oliver produced more than one million typewriters between 1895 and 1928.
