Smyth's theories on pyramid prophecy were then integrated into the works and prophecies of Charles Taze Russell (such as his "Studies in the Scriptures"), who founded the Bible Student movement (who adopted the name Jehovah's Witnesses in 1931, though Russell's successor, Joseph F. Rutherford, denounced pyramidology as unscriptural). Smyth's proposed dates for the Second Coming, first 1882 then many dates between 1892 and 1911, were failed predictions.
