Matthias Knutzen (also: Knuzen, Knutsen) (1646 – after 1674) was a German critic of religion and the author of three atheistic pamphlets. In modern Western history, he is the first atheist known by name and in person. Knutzen was called "The only person on record who openly professed and taught atheism" in the 1789 Students Pocket Dictionary of Universal History by Thomas Mortimer. Life Matthias Knutzen was born at Oldenswort (Schleswig-Holstein) early in 1646. His parents were Berend Knutzen, organist in Oldenswort and his wife Elisabeth (Elsebe). In the same year Knutzen was born his father died. As a boy, Knutzen was sent to his brother Johann Knutzen, an organist in Königsberg in East Prussia, and attended there a secondary school (the Altstädtisches Gymnasium) from 1661 to 1664. In 1664, he registered at the University of Königsberg and in 1668, at the University of Copenhagen, to study theology in its Lutheran seminary. In between he earned money as a private tutor. In 1673, he took a position as a village schoolteacher and auxiliary Protestant preacher in the Kremper Marsch (Schleswig-Holstein). However, he was dismissed at the end of 1673 because he had criticised ecclesiastical authorities in his sermons. In February 1674 he went to Rome and in September 1674 to Jena (Thuringia). There, Knutzen distributed handwritten atheistic pamphlets. The town and the University of Jena carried out an investigation. In order not to be arrested, Knutzen went first to Coburg and then to Altdorf near Nuremberg. On 22 October 1674, he was last seen in Jena. Then, all track of him is lost. The author Johannes Moller wrote in his biography of North German writers, Cimbria Literata (1744), that Knutzen had died in an Italian monastery, but that may have been an invention to discredit both Knutzen and the Roman Catholic church. Teachings In his three pamphlets of 1674, Knutzen claimed that there was a sect or community called the Gewissener or "Conscientarians" (i.e., 'the conscience people'). According to him, the Conscientarians had adherents in Hamburg, Jena, Paris, Amsterdam, and Rome, and, allegedly, more than 700 in Jena alone. This claim, however, is regarded as a fiction and the teachings which Knutzen spread as an alleged member of the Conscientarians were in fact his own. According to Knutzen, there are no transcendent entities such as God, the devil, or immortal souls, the Bible is implausible due to its many contradictions,
