マルセル・ブサック
After Ambiorix retired from racing, Marcel Boussac believed that he would have more value as a sire in the United States where the vast majority of race distances suited his record best. He was then sold for US$250,000 to a syndicate led by Bull Hancock, who brought him to stand at stud in time for the 1950 season at his Claiborne Farm near Paris, Kentucky.
