About Maria de Knuijt

Maria Simonsdr de Knuijt was a patron of the Dutch painter Johannes Vermeer. She provided support and financial assistance to Vermeer throughout his career. De Knuijt was married to Pieter van Ruijven, a wealthy citizen of Delft, in the Netherlands. Pieter had been identified as Vermeer's main patron, owning more than half of Vermeer's oeuvre. Scholarship in 2023 identified de Knuijt as the main patron, as she had known him for some time and was more directly involved with the artist. After van Ruijven and de Knuijt died, their estate was inherited by their daughter Magdalena. She died about one year after her mother, and the estate was then inherited by her husband Jacob Dissius and his father Abraham Dissius.
