When Lady Wallace died, she bequeathed much of her estate, including the art collections outside Hertford House, to Sir John Murray-Scott (1847-1912).
Sir John Murray-Scott came as a young man to work as Sir Richard's secretary and became Lady Wallace's closest friend and advisor in her final years. Murray-Scott suddenly found himself one of the wealthiest people in Europe and the owner of the rue Laffitte apartment and the château de Bagatelle in Paris, as well as further properties in London.
Whilst most of the finest pictures in the Wallace Collection had been brought to Hertford House, the other properties housed major collections of furniture, sculpture, tapestries and porcelain. During his lifetime Sir John sold Bagatelle to the city of Paris and on his death he bequeathed the rue Laffitte apartment and its contents to his friend Victoria, Lady Sackville, wife of the third Baron Sackville of Knole. Lady Sackville quickly sold the rue Laffitte collection to the Paris art dealer Jacques Seligmann, who dispersed it in subsequent years.
Works of art from this second Wallace Collection can now be found in museums and private collections throughout America and Europe.
