During the 1970's, the Church of Jesus Christ of Latter-day Saints (the "Mormon" church) went through four prophet/presidents. David O. McKay died in 1970, passing the leadership on to Joseph Fielding Smith. President Smith died in 1972, passing the position on to Harold B. Lee. Harold B. Lee died in 1973, after which Spencer W. Kimball took over.
