David Hyrum Smith (November 17, 1844 – August 29, 1904) was an American religious leader, poet, painter, singer, philosopher, and naturalist. The youngest son of Joseph Smith and Emma Hale Smith, he was an influential missionary and leader in the Reorganized Church of Jesus Christ of Latter Day Saints (RLDS Church). He was born approximately five months after the murder of his father. Joseph told Emma before he died what the child's name should be. From December 1847, David was raised by his mother and her second husband, Lewis C. Bidamon.
