Jan Claus (Strasbourg 19 June 1641 - Amsterdam, 8 March 1729) was a leading Quaker in Amsterdam. He was trained as a gold- and silversmith specializing in enamel and worked for a while in Cologne. In 1663 he travelled to Amsterdam where business prospects were not good. He was however given a letter of recommendation for a Londen goldsmith J.C. Follet, also from Strasbourg, who was a member of the Society of Friends. It was with Follet that Claus joined the Quakers. After his death - on 8 March 1729 - a collection of poems by family members and friends appeared in memory of Jan Claus.
