Wybrand Hendriks (June 24, 1744, Amsterdam – January 28, 1831, Haarlem) was a Dutch painter, primarily known for his portraits, and the concierge of the Teylers Museum.
According to the Netherlands Institute for Art History, he learned to paint while working in the decorative wallpaper factory of Johannes Remmers, in Amsterdam.
In 1775, he married Anthony Palthe's widow, Agatha Ketel, whom he had drawn previously in 1773, wearing mourning clothes.
[2] A painting he later made in 1791 of her sitting across from him at a table (probably situated in the fundatiehuis) was purchased for Teylers Museum with support from the Vereniging Rembrandt in 1999.
Hendriks was active as regent of the Vrouwe- en Antony Gasthuis hofje, a member of the Haarlem city council, and was a patriotic supporter of the French revolution at the end of the 19th century.
His paintings of the inner garden of the Foundation House and the Oval Room seem to have been created with the help of convex mirrors and other optical aids because the perspectives are impossible to achieve without this.
