CAMPBELL, Lewis Davis, diplomatist, born in Franklin, Ohio, 9 August, 1811; died 26 November, 1882. On leaving school he was apprenticed to a printer in 1828, and was afterward assistant editor of the Cincinnati "Gazette." He published a Whig newspaper at Hamilton, Ohio, from 1831 till 1836, supporting Henry Clay, and was then admitted to the bar and began to practice at Hamilton. He was elected to congress as a Whig, and served from 3 December, 1849, till 25 May, 1858, being chairman of the ways and means committee during his last term. He claimed to have been elected again in 1858, but the house gave the seat to C. L. Vallan-digham. He served as colonel of an Ohio regiment of volunteer infantry from 1861 till 1862, when he resigned on account of failing health. President Johnson appointed him minister to Mexico in December, 1865; but, before leaving for his post, he was a delegate to the Philadelphia union convert-tion and the Cleveland soldiers' convention of 1866. He sailed for Mexico, in company with General Sherman, 11 November, 1866, authorized to tender to President Juarez the moral support of the United States, and to offer him the use of our military force to aid in the restoration of law. Mr. Campbell remained in Mexico until 1868, and from 1871 till 1873 was again a member of congress.
