Hyrum Smith (February 9, 1800 – June 27, 1844) was an American religious leader in the Church of Jesus Christ of Latter Day Saints, the original church of the Latter Day Saint movement. He was the older brother of the movement's founder, Joseph Smith, and was killed with his brother at Carthage Jail where they were being held awaiting trial. Early life Hyrum was born in Tunbridge, Vermont, the second son of Joseph Smith Sr. and Lucy Mack Smith. Smith received a limited education, and established himself as a farmer. Smith attended Dartmouth College in his teens. This may have been one of the factors behind Dr. Nathan Smith treating Smith's brother Joseph's leg.
