Leading sire in Great Britain and Ireland (1964)

Chamossaire (1942–1964) was a British Thoroughbred racehorse and sire best known for winning the classic St Leger Stakes in 1945 and siring the Derby winner Santa Claus. After winning twice as a two-year-old, Chamossaire contested all three legs of the Triple Crown in 1945. He finished fourth in both the 2000 Guineas and the Derby before winning the St Leger. He was retired to stud where he proved to be a successful sire of winners. Chamossaire died in 1964.

Chamossaire’s sire Precipitation was a top class racehorse, best known for winning the Ascot Gold Cup in 1937. He went on to become a successful stallion, siring three other Classic winners in Airborne (Derby), Premonition (St Leger) and Why Hurry (Epsom Oaks), as well as the King George VI and Queen Elizabeth Stakes winner Supreme Court. Precipitation himself was sired by the unbeaten champion, Hurry On, making him a representative of the Godolphin Arabian sire line. Chamossaire's dam, Snowberry, was a very fast filly who won the Queen Mary Stakes at Royal Ascot. She was a daughter of Myrobella, the leading British two-year-old of 1932, making her a sister of the 2000 Guineas winner Big Game. Snowberry went on to produce Ariana, the grand-dam of the Epsom Derby winner Snow Knight. With a combination of stamina from his sire and speed from his dam, Chamossaire was regarded as having an excellent classic pedigree.
