Thorpe B. Isaacson

Henry Thorpe Beal Isaacson (September 6, 1898 – November 9, 1970) was a leader in The Church of Jesus Christ of Latter-day Saints (LDS Church), serving as a counselor in the First Presidency to church president David O. McKay from 1965 to 1970.

Isaacson was born in Ephraim, Sanpete County, Utah to parents Martin Isaacson and Mary Jemima Beal. He was ordained a high priest in 1941 by Charles A. Callis of the Quorum of the Twelve Apostles. In 1946 he became a second counselor in the Presiding Bishopric to Presiding Bishop LeGrand Richards, and then as first counselor to Presiding Bishop Joseph L. Wirthlin in 1952. In 1961 he was sustained as an Assistant to the Twelve Apostles.

On October 28, 1965, Isaacson was sustained as a counselor in the First Presidency to church president David O. McKay. Isaacson suffered a stroke on February 7, 1966, which severerly limited his activities as a counselor. Alvin R. Dyer was added as a counselor to the First Presidency to fill the role Isaacson was to perform. Isaacson was released from the First Presidency upon McKay's death on January 18, 1970, and resumed his former position as an Assistant to the Twelve.

Isaacson died in Salt Lake City, Utah.
