Astruc Remoch (sometimes spelled Raimuch) was a Jewish convert to Catholicism who made his mark in history by attempting the conversion of other Jews during the 14th century. Remoch was a medical doctor in Fraga, Spain in the 14th century. He had contact with prominent Jews of his day, such as of Zaragoza. The satirical poet Solomon ben Reuben Bonfed wrote his own much less careful reply to Remoch's arguments in a rhyming prose that attacked each of Remoch's arguments.
