JOHN LOGAN, M. D. was born in Hamilton county, Ohio, December 30, 1809, and is the son of James and Mary, nee Cooper, Logan, the former a native of Monaghan county, Ireland, and came to America in 1793; the latter of English descent. His father settled at Ellicott's Mills, in Maryland. In 1815 he removed to Missouri, to what is now known as Perry county. He remained there until 1826, when he went to Jackson county, Ill., where he died in 1852. Mrs. Logan died in 1828. John had but few school privileges in his boyhood, but by his own efforts acquired a fair English education. In 1831, at the breaking out of the Indian troubles, he was elected Major of the 9th regiment, Illinois militia, and in 1832 served in the Black Hawk war. In September, 1836, he was elected Colonel fo the 44th regiment, Illinois militia. In 1833 he came to Carlinville, and worked at the carpenter trade. He had, however, previous to this, read medicine, with a view of adopting it at some future time as a profession. He continued at the carpenter trade until 1836, after which he again went to reading medicine. He commenced the practice in 1838, in partnership with Dr. James, with whom he remained until 1841. He, in the winter of 1840, attended a course of lectures at Kemper College, St. Louis, and in 1841, at the St. Louis Hospital, under Professor Joseph N. McDowell, after which he began his practice again, continuing with growing success until 1861. At the breaking out of the late war he was one among the first to advise the immediate raising of troops to put down the rebellion. On the 31st of December, 1861, the 32d regiment, Illinois Volunteers, were mustered into service. Dr. Logan was elected Colonel. He first reported with his men to Gen. Grant, at Cairo, Illinois, in January of 1862. After the battles of Forts Henry and Donaldson, his regiment became a part of the Fourth Division of the Army of the Tennessee, under command of Gen. S. A. Hurlburt. The regiment made for itself a most honorable record, being continually at the front. At the battle of Shiloh, the regiment entered the fight with five hudnred and forty men, and came out with two hundred and five killed and wounded. He was mustered out of service December 30, 1864, but served on the court-martial of Genearl Sweeney until the 22d of February, 1865. In 1866 he was appointed United States Marshall for Southern Illinois. He held the office until 1870. After retiring from his duties as Marshall he resumed his profession of medicine in Carlinville.

On the 31st of January, 1841, he was united in marriage with Miss Ann Eliza Banks, who is a native of Kentucky, but was a resident of St. Louis at the time of her marriage. Her parents were Virginians. Ten children have been born to them, five of whom are living. The eldest son, William D. D., was first lieutenant of Co. "C" 32d regiment, Illinois Volunteers. He contracted a disease from overwork and exposure, and died while in the service. In religious belief Dr. Logan is a Methodist, and has been since he was seventeen years of age. In politics he is a Republican, and was one of the original Abolitionists who voted for Birney, the Abolition candidate for president in 1844. He has been all his life an exceedingly temperate man. In his character he illustrates the most sterling qualities. Prompt and zealous, he is at the same time generous and warm-hearted. As a soldier his services were marked by an efficiency surpassed by none. As a civil officer he was honest, capable and popular, while in his professional career he is skilful, and in the performance of his work combines the noblest characteristics of a true Christian manhood.
