Luke Samuel Johnson[3] (November 3, 1807 – December 9, 1861) was a leader in the Latter Day Saint movement and an original member of the Quorum of the Twelve Apostles from 1835 to 1838.

[4] He wrote of his family in an autobiographical sketch:[5] My grandfather, Israel Johnson lived in Chesterfield, New Hampshire, and was much respected by his neighbors for his honesty, integrity and industry.

My father was satisfied in regard to the truth of "Mormonism" and was baptized by Joseph Smith, Jun., in the winter of 1830–31, and furnished him and his family a home, while he translated a portion of the Bible.Johnson was an educator and a physician.

After Susan's death on September 20, 1846, he married America Morgan Clark on March 3, 1847, in Council Bluffs, Iowa, and had additional children.

This family included Susan Marinda, Orson Albert, Mark Anthony, Charlotte Elizabeth, Lovinia Ann, Phebe W. and Luke.

After leaving the church, Johnson moved to Cabell County, Virginia, where he taught at Marshall Academy and then studied medicine, ultimately setting up a medical practice in Kirtland.

Johnson traveled with Brigham Young and Wilford Woodruff to the Salt Lake Valley, serving as a captain of ten, as part of the first group of 143 Mormon pioneers in July 1847.

[citation needed] Johnson settled in St. John, Tooele County, Utah, where he served as bishop of a local LDS congregation.
