Frederic Count de Thoms

Part of his art collection is still on display in the Dutch National Museum of Antiquities and in the Geldmuseum [nl] in Utrecht.

After he settled in the Dutch city of Leiden, part of the collection was placed in Oud Poelgeest, the castle of his wife's family.

During his stay in Holland De Thoms invested a lot of time and money in the private museum he was planning for himself.

After De Thoms' death at Leiden in 1746, the collection was sold to Dutch stadtholder William IV, Prince of Orange, for 30,000 guilders.

The collection stayed in the Orange family until Napoleon's troops conquered the Netherlands and seized all art for transportation to Paris.
