Joseph F. Smith died on 19 November 1918. He had six wives and forty-eight children, including apostles Hyrum M. and Joseph Fielding, and David A., a member of the Presiding Bishopric of the Church.
Smith dies. His last words are to Apostle Heber J. Grant: "Always remember this is the Lord's work, and not man's. The Lord is greater than any man. He knows who He wants to lead His Church, and never makes any mistakes." Smith is the only LDS president to be buried without a public funeral (due to the epidemic of the "Spanish Influenza").
