Frank Butler was an English jockey who became one of the country's top riders. In a period of about 11 years he won The Derby twice, The Oaks on six occasions, the Two Thousand Guineas twice, the One Thousand Guineas twice, the St Leger, the Goodwood Cup on three occasions and the Triple Crown on West Australian. In his final years of racing he won 143 races from 384 starts. Illness forced him to stop riding in 1854 and he died two years later at the age of 39.

Samuel "Sam" Chifney, also known as Sam Chifney Sr., Sam Chifney the Elder or Old Sam Chifney to distinguish him from his son, was an English jockey. He was a pioneer of professional race-riding, developing a trademark late finishing style, known as the 'Chifney rush' and was the retained jockey of the Prince of Wales. He became the leading horseman of his day, winning four runnings of the Oaks and one of the Derby, but his career ended in ignominy after a scandal around a ride on the Prince of Wales's horse, Escape. Despite inventing a bit for horses that is still in use today, he died in debtors' prison in London.
