Alexander Campbell was a physician, political leader and elected official in the early years of Ohio statehood.
Campbell was born in Frederick County, Virginia, in 1779. He moved with his parents to Tennessee and then to Kentucky, where he received his formal education at the Pisgah Academy. Following graduation from the Academy, Campbell enrolled in Transylvania University to study medicine. In 1803, Campbell began a political career and served in the Kentucky House of Representatives. In 1804, he moved to Adams County, Ohio, and then to Brown County. He continued to practice medicine but returned to politics as well. He served in the Ohio House of Representatives from 1807 to 1809 and was the Speaker of the House during his last two years in office.
In 1809, Campbell became one of Ohio's two United States Senators. Senator Edward Tiffin had resigned and Campbell was appointed to replace him. Campbell held the seat until 1813. He was not in attendance when the United States Senate approved a declaration of war against England that began the War of 1812. Ohio's other Senator, Thomas Worthington, voted against the war. Upon completion of his Senate term, Campbell returned to Ohio and remained active involved in state politics. He served in the House of Representatives (1819 and 1832-1833) and also in the Ohio Senate (1822-1824). He unsuccessfully ran for governor of Ohio in 1826. He was an abolitionist and favored the political philosophy of first the Democratic-Republican Party and then of the Democratic Party. The last elected office that Campbell held was as mayor of Ripley, Ohio, from 1838 to 1840. Campbell died in Ripley on November 5, 1857.
