Samuel Sullivan was the fourth Ohio State Treasurer from 1820 to 1823. He was the first manufacturer of fine pottery in Zanesville, Ohio.

The treasurer of the U.S. state of Ohio is responsible for collecting and safeguarding taxes and fees, as well as managing state investments. The Treasury was located in the Ohio Statehouse from 1861 to 1974, when it was moved to the Rhodes State Office Tower. The original office in the statehouse, which has been restored to its 19th-century appearance, is used for ceremonial events.
