US financier and investment banker Clarence Dillon (1882-1979) was born under the name of Clarence Lapowski. His father Samuel Lapowski was a Polish-Jewish immigrant. Clarence Dillon bought the majority in 1916 in the later renamed "Dillon, Read & Co" investment bank. In 1935 he bought the famous Graves Winery Château Haut-Brion
supposedly because he appreciated this wine (see in detail there). His son Clarence Douglas Dillon (1909-2003) was US ambassador to Paris and from 1961 to 1965 finance minister under Presidents John F. Kennedy and Lyndon B. Johnson. This acquired in 1983 exactly opposite Château La Mission Haut-Brion
, as well as the nearby wineries Château La Tour-Haut-Brion
and Château Laville-Haut-Brion
, Finally, in 2011, there were also the Saint Emilion wineries Château L'Arrosée
and Château Tertre-Daugay
(now Château Quintus). From 1979, the family empire was led by daughter Joan Dillon, a Duchesse de Mouchy. Her successor is since 2001, her son Prince Robert of Luxembourg.
