Joseph Fielding Smith Sr. (November 13, 1838 – November 19, 1918) was an American religious leader who served as the sixth president of The Church of Jesus Christ of Latter-day Saints (LDS Church). He was the nephew of Joseph Smith, the founder of the Latter Day Saint movement, and was the last president of the LDS Church to have known him personally. Smith was the son of church patriarch Hyrum Smith and his second wife, Mary Fielding, a British convert to the church who married Hyrum after the death of his first wife, Jerusha Barden Smith (1805–1837). In addition to her two children, Mary also raised the six children born to Hyrum and Jerusha. Less
