Dutch draughtsman and engraver, part of a family of painters, brother of Hendrik Kobell. In addition to portraits, his work was devoted primarily to prints of contemporary historical and allegorical subjects. His most important works, however, were the coloured prints of anatomical subjects made for Jan Bleuland, Professor of Anatomy and Physiology at Utrecht University. Jan I lived in Gouda from 1789 to 1795. //
