Johannes Mathesius (June 24, 1504 – October 7, 1565), also called Johann Mathesius or John Mathesius, was a German minister and a Lutheran reformer. He is best known for his compilation of Martin Luther's Table Talk, or notes taken of Luther's conversation and published afterwards. He rivaled Anton Lauterbach in his diligence in notetaking, and surpassed him in the discrimination with which he arranged it. Source: Wikipedia (en)
