Johannes Thopas (ca. 1626 – 1688/95), born deaf, was one of the few artists in the Golden Age who specialized in drawn portraiture. He was especially a virtuoso in lead marker on parchment.
His earliest known works from 1646, in the collection of the Fondation Custodia in Paris, show that Thopas was a particularly talented draftsman from an early age. He portrayed both famous and unknown people.
The artist was born in Arnhem, after the death of his father his mother remarried a mayor of Emmerich. After that Thopas worked in Amsterdam, Haarlem and Assendelft, because of his disability always under the care of a guardian and living with relatives.
