Abraham Willet (1825âÂÂ1888) was a Dutch art collector and amateur painter.
Willet was born in Amsterdam and married Louisa Holthuysen on 17 July 1861.
Willet was a member of Arti et Amicitiae. For years, his art collection was considered the basis of the Willet-Holthuysen museum collection, but recent research has shown that his wife was perhaps more influential in forming the collection.
