Throughout his long life, Martin Harris (fig. 1) consistently testified that he knew Joseph Smith translated the Book of Mormon from golden plates. At first affiliated with Joseph Smith and the main body of The Church of Jesus Christ of Latter-day Saints, for a time Harris associated with a schism led by James J. Strang. He served a mission in England in 1846 for the Strangites, but he claimed to the end of his life that he never preached against Mormonism or against the Book of Mormon. Indeed, he was a powerful witness of the Book of Mormon during his mission.
