RODRIGUES, DIONISIUS (Diniz; d. 1541), Marrano physician to the kings Emanuel and John III of Portugal. In 1518 he engaged in a once-famous controversy with the French physician Pierre Brissot on the rival systems of bloodletting of Galen and Hippocrates. Threatened as a Judaizer by the Inquisition (which subsequently burned him in effigy), he fled first to London where he was a member of the crypto-Jewish community under Henry VIII, then to Antwerp, and finally to Ferrara, where he died. He was the father of the eminent medical writer Manuel *Brudo.
