Count Antoine Seilern (17 September 1901 – 6 July 1978) was an Anglo-Austrian art collector and art historian. He was considered, along with Sir Denis Mahon, to be one of a handful of important collectors who was also a respected scholar. The bulk of his collection was bequeathed anonymously to the Courtauld Institute of Art. Known as the "Princes Gate bequest", most of it is on display at the Courtauld Gallery in London.Brown, Christopher. “London.
