In this way he acquired old master paintings such as Ghirlandaio's portrait of Giovanna Tornabuoni (once in the Morgan Library) and Carpaccio's Knight (from the collection of Otto Kahn).[1] The collection was later expanded by Heinrich's son Baron Hans Heinrich Thyssen-Bornemisza (1921–2002),[4] who assembled most of the works from his relatives' collections and proceeded to acquire large numbers of new works (from Gothic art to Lucien Freud).
