LOGAN, Stephen Trigg, jurist, born in Franklin county, Kentucky, 24 February, 1800; died in Springfield, Illinois, 17 July, 1880. He was educated at Frankfort, Kentucky, and when only thirteen years of age was employed as a clerk in the office of the secretary of state. He went to Glasgow, Kentucky, in 1817, studied law, and was admitted to the bar before he was twenty-one, but did not at once engage in practice. Subsequently he was appointed commonwealth's attorney, and followed his profession for ten years in Barren and the adjoining counties.
Becoming pecuniarily embarrassed, he emigrated in 1832 to Sangammon county, Illinois, and in the following spring opened a law-office in Springfield, where he soon won reputation throughout the state. In 1835 he was elected judge of the 1st judicial circuit of the state, and in 1842 he was chosen to the legislature, and again in 1844 and 1846. In 1847 he was a delegate to the convention that framed the Illinois constitution. His efforts, both in the legislature and in the convention, were specially directed to securing economy in the public expenditures, and to making adequate provision for the payment of the state debt.
For the next six years he devoted himself exclusively to his profession, and from 1841 till 1844 had as his law-partner Abraham Lincoln. In 1854 he was elected for the fourth time to the lower branch of the general assembly. In 1860 he was a delegate from the state at large to the Chicago Republican national, convention, and early in February, 1861, he was appointed by the governor of Illinois one of five .commissioners to represent the state in the National peace convention at Washington, in which he took an active part. This was Judge Logan's last appearance on any great public occasion.
He retired soon afterward from politics, and gradually withdrew from the pursuit of his profession, but maintained his interest in current events. As an advocate he stood at the head of the bar in his adopted state. Judge David Davis has said of him" "In all the elements that constitute a great 'nisi prius' lawyer, I have never known his equal." See "Memorials of the Life and Character of Stephen T. Logan " (Springfield, II1., 1882).
