Adriaan van der Willigen Pz. (20 September 1810, Hillegom - 22 August 1876, Rheden)[1] was a 19th-century medical doctor and historian from the Northern Netherlands.
According to the RKD he was born in Hillegom, the son of Pieter van der Willigen and a nephew of Adriaan van der Willigen, who left him an art collection and library which he expanded.[2] He was married 29 May 1845 to Geertruyda Aletta van Voorthuysen and set up a practise in Haarlem, where he became a member of Teylers Tweede Genootschap. Like his uncle whom he was named after, he had a great love of art history and wrote many important works on Dutch painters as a result of research in the Haarlem archives, most notably on the members of the Haarlem Guild of St. Luke.[2] In later years he had to leave his practise due to illness and moved to Rhedersteeg, where he later died.[2]
