David O. McKay
David Oman McKay (September 8, 1873 – January 18, 1970) was the ninth president of The Church of Jesus Christ of Latter-day Saints (LDS Church), serving from 1951 until his death. Ordained an apostle and member of the Quorum of the Twelve Apostles in 1906, McKay was a general authority for nearly 64 years, longer than anyone else in LDS Church history, except Eldred G. Smith (though Smith was not active as a general authority for many years).
