Gerrit de Graeff, vrijheer van Zuid-Polsbroek, Purmerland and Ilpendam (24 February 1766, Amsterdam - 16 December 1814) was a member of the influential De Graeff family of Amsterdam. He belonged to the patrician class of the city and held the feudal titles Free Lord of Zuid-Polsbroek as those of Purmerland and Ilpendam.
Gerrit de Graeff was a son of Gerrit de Graeff (II) van Zuid-Polsbroek, patrician of Amsterdam and Christina van Herzeele.[1] In 1794 he married to Emilia Henriette Stadlander (1766–1826).[2] The couple had four children:[3]
The family of Gerrit de Graeff lived at Herengracht in a mansion, now the Tassenmuseum Hendrikje. Most of the time he resided at his castle Ilpenstein, and he also owned the country estate Bronstee near Heemstede. At Ilpenstein, De Graeff owned a big art collection, including paintings from Rembrandt van Rijn, Gerard Ter Borch and Jacob van Ruisdael. The collection included some famous paintings like Catharina Hooft with her Nurse, painted by Frans Hals, and the Pickenoys representative Marriage portraits from Cornelis de Graeff and Catharina Hooft. Both now can be seen at the Gemäldegalerie, Berlin.
In 1811 De Graeff inherited the Vrijheerlijkheiden Zuid-Polsbroek, Purmerland and Ilpendam from his father. He was also President-Hoofdingeland of the Purmer (Water Board).[1] He died only three years after his father. His only son Gerrit succeeded him as Free Lord of Zuid-Polsbroek, Purmerland and Ilpendam in 1814.[2]
