Henry Cecil

Assistant de son beau-père, Sir Cecil Boyd-Rochfort entre 1964 et 1968, il s'installe ensuite à son compte et bâtit un des plus beaux palmarès des courses anglaises. Tête de liste des entraîneurs à 10 reprises, il remporte une trentaine de courses classiques et détient le titre d'entraîneur le plus titré du meeting de Royal Ascot jusqu'en 2018. Il est notamment l'entraîneur de Frankel, l'un des plus grands champions de l'histoire. Il a reçu le Daily Telegraph Award of Merit en 2005.

Après son décès, c'est son épouse Lady Cecil qui reprend les rênes de son écurie, avant de se retirer en 2015[3].
