| Nathan Kimball was born on November 22, 1822, in Fredericksburg, Indiana. He attended what is now known as DePauw University, then worked as a teacher, farmer and physician. After serving in the Mexican
War as a captain of 2nd Indiana volunteers, he returned to his medical practice until the beginning of the Civil War.
Returning to the army, Kimball became colonel of the 14th Indiana on June 7, 1861. He took part in operations in Cheat Mountain in September, and at the battle of Greenbrier in October, 1861. He fought well at Kernstown in 1862, defeating Confederate Maj. Gen. Thomas J. “Stonewall” Jackson. This was one of the few tactical victories ever achieved over Jackson. Promoted to brigadier general on April 16, 1862, he fought at Antietam, where his brigade held its ground with desperate courage, losing nearly six hundred men. At Fredericksburg he was wounded in the thigh, but returned to service after his recovery. In the summer of 1863 he commanded a division of the XVI corps in the siege of Vicksburg. He also took part in the Atlanta Campaign first as a brigade then as a commander in the IV Corps. Kimball was brevetted Major General in 1865 and soon after the end of the war became state commander of the newly organized Grand Army Of The Republic (he had been mustered out of the service on 24 August 1865).
Nathan Kimball then became state treasurer and legislator. He moved west in 1873, and was appointed surveyor general of Utah by President Ulysses S. Grant and postmaster of the city of Ogden. He died in Ogden, on January 21, 1898.
