Among his best-known owners was Sir Winston Churchill. Among the 70 winners he trained for him were the French-bred grey Colonist II, who became Sir Winston’s first winner when scoring first time out in England in August 1949. By the end of his career Colonist II had won 13 races including the Jockey Club Cup and a hugely popular victory on the Winston Churchill Stakes at Hurst Park. Others included Welsh Abbot (1958 Portland Handicap), Tudor Monarch (1959 Stewards’ Cup), High Hat, who beat Petite Etoile in the Aly Khan Memorial Gold Cup at Kempton Park in 1961, and Vienna, who finished third to St Paddy in the 1960 Derby.
