Johannes or Johan Teyler (23 May 1648 – c.1709) was a Dutch Golden Age painter, engraver, mathematics teacher, and promoter of the technique in color printmaking now known as à la poupée.
[2] After the death of his father, he studied in Leiden and afterwards acquired a post as Professor of Math and Philosophy in Nijmegen in 1670.
[2] Through the mediation of his friend Gottfried Leibniz he attempted to acquire a professorship in Wolfenbüttel but gave up after discussions with Christiaan Huygens.
With the extra funds he undertook a trip to Italy, Egypt, the Holy Land and Malta, and later sent his diary to the Elector.
[3] They knew each other from their time in Rome as members of the Bentvueghel club, where Teyler also consorted with his former Math pupil from Nijmegen Jan van Call.
