The Belgian painter Isidoor Opsomer made a portrait of Henry van de Velde in 1943. Hammacher wishes to acquire this work in 1957, because ‘it gives a dynamic impression of the appearance of the architect and of our museum’ and ‘was painted in precisely those years when he was working on the extension of the museum’. Although there are other interested parties – including museums in Antwerp, Van de Velde’s birthplace – Opsomer is prepared to sell the portrait to the Rijksmuseum Kröller-Müller for 5,000 guilders, half the asking price.
Hammacher emphasizes to the Oversight Committee that the portrait has a historical significance in the collection: ‘This completes the series of painted likenesses of the key figures in the history of the museum: Mrs Kröller by Floris Verster – Minister Marchant by Dirk Nijland – Bremmer by Floris Verster – Van de Velde by Opsomer’.
