William Yworth or Yarworth (Dutch: Willem IJvaert) (died 1715) was an Anglo-Dutch distiller, alchemist, and physician who collaborated with Isaac Newton. He wrote a number of tracts on distilling and alchemy. Two of his alchemical works, Mercury′s Caducean Rod (1702) and Trifertes Sagani, or Immortal Dissolvent (1705) appeared under the pseudonym Cleidophorus Mystagogus. Cleidophorus is the Latinized form of the Greek kleidophoros (κλειδοφόρος), meaning "key bearer," and Mystagogus is, of course, a Latin term for a mystagogue. Yworth was associated with a number of Quakers and buried in a Quaker cemetery at Woodbridge, Suffolk, which, as Wallworth observes, suggests that he may have been a Quaker.
