Besides purchases, private donations have been of incalculable value for the creation of the collection.
The Hague collector A.A. des Tombe (1818-1902) left twelve important paintings to the Mauritshuis. One of them is the now world-famous and favourite Girl with a Pearl Earring by Vermeer.
The Mauritshuis also owes much to Abraham Bredius (1855-1946). As a museum director, he acquired many paintings for the collection, but he also donated 25 paintings upon his death. These included no less than three works by Rembrandt: Andromeda, Homer and Saul and David.
In 1936, Sir Henri Deterding (1866-1939) donated five important paintings to the museum, including Girl Eating Oysters by Jan Steen and Gerard ter Borch's Woman writing a letter.
Louise Thurkow-van Huffel (1900-1987) bequeathed three paintings, including a Sea View by Salomon van Ruysdael.
In 2002, Willem baron van Dedem (1929-2015) donated five paintings to the Foundation Friends of the Mauritshuis. These included a Still Life by Willem Kalf, a Brazilian Landscape by Pieter Post and Peasants Dancing outside a Bohemian Inn by Roelant Savery.
