Brigham Young (6/1/1801 – 1877) was born in Whitingham, Vermont. He became a member of the Church of Jesus Christ of Latter-day Saints in 1832. He followed Joseph Smith through Ohio, Missouri, and Illinois. He was ordained to the Quorum of the Twelve Apostles in 1835. His missionary efforts, which proved to be very successful, led him to England in 1840. He returned to the United States and became the president of the Quorum of the Twelve and became more involved in the development and leadership of the Church. Finally, after the death of Joseph Smith in 1844, he became the second prophet of the Mormon church and filled that position until his death in 1877.
As the head of the LDS church, in 1846 Brigham Young began the move westward by leading the Mormons to what is now Utah. They arrived there in 1847.
Brigham Young gave many sermons as Church Leader which have been recorded, word for word, in the Journal of Discourses.
