David Arthur Haycock (September 4, 1916 – February 25, 1994)[1][2] was a personal secretary to several twentieth-century presidents of the Church of Jesus Christ of Latter-day Saints (LDS Church), including George Albert Smith, Joseph Fielding Smith, Harold B. Lee, Spencer W. Kimball and Ezra Taft Benson.
Haycock also accompanied these leaders on their many trips throughout the world where he aided in the planning and note taking of meetings.
Following his return from missionary service, he married Maureen McCellen, took a job at the Deseret News, and was later appointed as George Albert Smith's personal secretary.
Upon McKay's death, he became personal secretary to Joseph Fielding Smith and aided in his travels.
Haycock also read several of Kimball's talks when he was unable to address general conference sessions himself.
