The Oliver Typewriter Company was an American typewriter manufacturer headquartered in Chicago, Illinois. The Oliver Typewriter was the first effective "visible print" typewriter, meaning text was visible to the typist as it was entered. Oliver typewriters were marketed heavily for home use, utilizing local distributors and sales on credit. Oliver produced more than one million machines between 1895 and 1928 and licensed its designs to several international firms. Competitive pressure and financial troubles resulted in the company's liquidation in 1928. The company’s assets were purchased by investors who formed The British Oliver Typewriter Company, which manufactured and licensed the machines until its own closure in the late 1950s. The last Oliver typewriter was produced in 1959.

Thomas Oliver was awarded his first typewriter patent, US Patent No. 450,107, on April 7, 1891. After four years of development, a "crude working model" composed of 500 parts had been produced. Oliver resigned his ministry and moved to Epworth, Iowa, where he found investors willing to provide $15,000 of capital, and leased a building in which to manufacture his machines.
