Early Settler, Clockmaker, War of 1812 Veteran
Military Service: Phineas Deming served as a private from August 24 to November 11, 1812, in Captain Asa Hutchins' Company, 3rd (Hayes') Regiment, Ohio, Militia, during the War of 1812. Capt. Hutchins' company contained many men from Vienna Township, including fellow clockmaker Lambert W. Lewis.
Phineas Deming, probably in partnership with Thomas Lewis, manufactured wooden-work clocks in the in Vienna Township between 1828 and 1832. His place of business was located on a lot through which Little Yankee Creek ran, on Sodom-Hutchins (now Sodom-Hutchings) Road, approximately a mile and a half north of Woodford's Corners. He signed his clocks "P. Deming."
An early settler in Vienna, Deming purchased land in the Township in 1816. His business was financed through a $500 mortgage with clock pedlar Thomas Lewis. Though it is not clear whether the business was a factory or an assembly shop, the business employed six men between 1828 and 1830.
Deming's career as a clock manufacturer mirrored in many respects those of other Vienna clockmakers. Overextension of credit through mortgages, reduced demand for clocks, and an economic depression in the early 1830s essentially ended the clockmaking "boom" in Vienna and Trumbull County.
Deming may have lost the business to Lewis, for he left the business in 1830. He left Vienna Township in 1834.
