In December 1905, The Church of Jesus Christ of Latter–day Saints celebrated the one hundredth birthday of its founder, Joseph Smith. A granite monument was erected at his birthplace in Sharon, Vermont, and gatherings of Saints were held in congregations in Utah and other western states. The Church at this time was under investigation and criticism from federal and local government and religious figures, and the erection of the monument generated some negative attention. This article documents the celebration in the Tabernacle in Salt Lake City with photos of the elaborate decorations prepared for the anniversary celebration. About eighty people who had known Joseph Smith during his life were honored guests.
