Joseph Fielding Smith Jr. was born on July 19, 1876, into a prominent family within the Church of Jesus Christ of Latter-day Saints. He was the son of Joseph F. Smith, a former church president, and the great-nephew of the church's founder, Joseph Smith. His lineage placed him in a unique position within the church, and he would go on to have a significant impact on its history.
In 1910, Smith was called to the Quorum of the Twelve Apostles, a pivotal role he held while his father served as president of the church. His leadership journey culminated in 1970 when he became the tenth president of the LDS Church at the remarkable age of ninety-three years and six months, making him the oldest individual to assume this position in the church's history.
Smith's tenure as President of the Quorum of the Twelve Apostles lasted from nineteen fifty-one to nineteen seventy, marking the third-longest service in that capacity. He served throughout the presidency of David O. McKay, contributing to the church's growth and direction during a transformative period.
As a religious scholar and prolific writer, Smith dedicated many years to the role of Church Historian and Recorder. His works have become essential references for church members, reflecting his deep commitment to the faith. Known for his rigid orthodoxy, he held conservative views on various issues, including evolution and race, although it is noted that his advanced age led to a more accommodating stance towards reforms during his presidency.
