Resumen de Nogmaals over een oud raadsel: Jacob van Ruisdael, Arnold Houbraken en de Amsterdamse naamlijst van geneesheren
In 1932 Wijnman published an article on the life of Jacob van Ruisdael and other members of his family in "Oud Holland". There has been much speculation over Ruisdael being a phisician as well as an artist ever since. Wijnman found the artist´s name in a professional list of Amsterdam´s doctors, which supported Houbraken´s statement, published in 1721, that Ruisdael had performed operations. This article refers to evidence from medical and academic history which has not been taken into consideration so far. In the light of new arguments, Wijnman´s claim regarding Ruisdael´s medical career has become questionable.
