Marcel Boussac
At his self-titled estate "Aiglemont", in the town of Gouvieux in the Picardy region of France – about 4 kilometres (2½ miles) west of the Chantilly Racecourse – the Aga Khan operates the largest horse racing and breeding operation in the country. In 1977, he paid £1.3 million for the bloodstock owned by Anna Dupré and in 1978, £4.7 million for the bloodstock of Marcel Boussac.
