The World Will Come to an end on 1533 Oct 19

Michael Stifel : mathematician
In 1532 Stifel published anonymously his "Ein Rechenbuchlin vom EndChrist. Apocalyps in Apocalypsim" (A Book of Arithmetic about the AntiChrist. A Revelation in the Revelation). This predicted that Judgement Day the world would end at 8am on October 19, 1533. When this prediction failed, he did not make any other predictions.
