Charles Scott Venable (March 19, 1827 – August 11, 1900) was a mathematician, astronomer, and military officer. In mathematics, he is noted for authoring a series of publications as a University of Virginia professor.

He was born in Virginia and graduated from Hampden-Sydney College at the age of 15. For several years following his graduation, he served as a mathematics tutor at the college. He received further education at the University of Virginia as well as in Berlin and Bonn, Germany. He became a professor in mathematics and astronomy in Virginia and South Carolina.

Venable was present at the firing on Fort Sumter in April 1861, serving as a lieutenant in the South Carolina state militia. He then fought as a private in Company A, 2nd South Carolina Infantry. In the spring of 1862, Venable joined the staff of presidential military advisor General Robert E. Lee as an aide-de-camp with the rank of major. He continued serving on Lee's staff when the general took command of the Army of Northern Virginia on June 1, 1862. He served on Lee's staff from the Peninsula Campaign to Appomattox Court House and was promoted to lieutenant colonel.

Following the war, Venable resumed his career as an educator. During a visit to Prussia, he was invited to the castle of Heros von Borcke, the former aide-de-camp to General J.E.B. Stuart.[1]
