About Joseph F. Smith
Joseph Fielding Smith Sr. was an American religious leader who served as the sixth president of the Church of Jesus Christ of Latter-day Saints. He was a nephew of Joseph Smith, founder of the Latter Day Saint movement, and the last LDS Church president who had personally known him. At the age of fifteen, Smith was called to go on his first LDS mission to the Sandwich Islands under the direction of apostle Parley P. Among the church members in that city was William Fowler; Smith was present at the meeting where Fowler's hymn "We Thank Thee, O God, for a Prophet" was first sung.
