マルセル・ブサック
He was still an apprentice to John L Jarvis when he won his first jockey's title (which he shared with Steve Donoghue) in 1923. He won again the following year, with a total of 106 winners. After this, he spent a large part of his riding career in France, riding for Marcel Boussac. He would return to France after he finished riding in 1953 to train for him as well.
