Stephen L. Richards (18 June 1879 – 19 May 1959) born in Mendon, Utah, was a member of the Quorum of the Twelve Apostles of The Church of Jesus Christ of Latter-day Saints from January 8, 1917, to April 9, 1951. Elder Richards also served as First Counselor in the First Presidency of the Church under President David O. McKay from April 9, 1951, until his death.
Elder Richards was the grandson of Willard Richards, an early Apostle of the Church at the time of Joseph Smith. Elder Stephen L. Richards himself was the son of Stephen Longstroth Richards and Emma Louise Stayner. In fact, Elder Richards' father and George F. Richards were half-brothers, since they were both children of Nancy Longstroth, who after the death of her first husband, Willard, married Willard's nephew, Franklin D. Richards.
