L'Abbesse de Jouarre (1886 – 6 March 1897) was a Thoroughbred racehorse that won the 1889 Epsom Oaks.
 The horse was owned by Lord Randolph Churchill and the Earl of Dunraven during her three-year racing career.
 She was nicknamed "Abscess on the Jaw" during her career due to the difficulty the public had pronouncing her name.
 A versatile racehorse, she was able to win major races at distances ranging from six furlongs to one and a half miles.
 Retired from racing in 1891, L'Abbesse was the dam of the influential German broodmare Festa and the leading stallion Desmond.
 L'Abbesse de Jouarre died 6 March 1897 during foaling.
The Oaks Stakes is a Group 1 flat horse race in Great Britain open to three-year-old fillies.
 It is run at Epsom Downs over a distance of 1 mile, 4 furlongs and 6 yards , and it is scheduled to take place each year in early June.
 It is the second-oldest of the five Classic races, after the St Leger.
 Officially the Investec Oaks, it is also popularly known as simply The Oaks.
 (Increasingly it is coming to be referred to as the Epsom Oaks in both the UK and overseas countries, although 'Epsom' is not part of the official title of the race.)
Diminuendo (9 February 1985 – 2010) was an American-bred, British-trained Thoroughbred racehorse and broodmare best known for winning the classic Epsom Oaks in 1988.
 She was one of the best two-year-old fillies of 1987, when she won all four of her races including the Cherry Hinton Stakes and Fillies' Mile.
 In 1988 she was beaten in her first two races, but won her next four, taking the Musidora Stakes, Epsom Oaks, Irish Oaks and Yorkshire Oaks.
 She finished second when favourite for the St. Leger Stakes and ended her racing career by finishing unplaced in the Prix de l'Arc de Triomphe, but was rated the best three-year-old filly of the season in Europe.
 She was then retired to stud, where she had some success as a broodmare.
Trial races for the Epsom Oaks are horse races during April and May which are contested by three-year-old fillies likely to run in the Epsom Oaks in early June.
Lord Randolph Henry Spencer-Churchill (13 February 184924 January 1895) was a British statesman.
 Churchill was a genuine Tory radical, who coined the term Tory Democracy.
 He inspired a generation of party managers, created the National Union of the Conservative Party, broke new ground in modern budgetary presentations, attracting admiration and criticism alike from across the political spectrum.
 His most acerbic critics resided in his own party among his closest friends; but his disloyalty to Lord Salisbury was the beginning of the end of what should have been a glittering career.
 His devoted son, Winston, who hardly knew his father in life, wrote a biography of him.
Light Shift (22 March 2004 – 2014) was an American-bred, British-bred Thoroughbred racehorse and broodmare best known for winning the 2007 Epsom Oaks.
 In a racing career which lasted from June 2006 to October 2007 the filly ran nine times and won four races.
 After winning once as a two-year-old, Light Shift won the Cheshire Oaks on her second appearance as a three-year-old.
 She then won the Classic Oaks over one and a half miles at Epsom, beating the Irish filly Peeping Fawn.
 Light Shift never won another race, being beaten by Peeping Fawn in the Irish Oaks and the Nassau Stakes and finishing unplaced in the Prix de l'Opera.
Lady Carla (8 March 1993 – 2012) was a British Thoroughbred racehorse and broodmare best known for winning the Epsom Oaks in 1996.
 In a racing career which lasted from October 1995 to July 1997 the filly ran six times and won three races.
 After winning her only race as a two-year-old, Lady Carla won the Listed Oaks Trial Stakes at Lingfield Park on her three-year-old debut.
 Four weeks later she maintained her unbeaten run in the Classic Oaks over one and a half miles at Epsom, winning by nine lengths.
 She was beaten when favourite for the Irish Oaks and finished unplaced in two races the following season before being retired to stud.
Jet Ski Lady (foaled 20 February 1988) was an American-bred, Irish-trained Thoroughbred racehorse, best known for winning the Epsom Oaks in 1991.
 In a racing career which lasted from June 1990 to October 1991 the filly ran ten times and won four races.
 After winning twice as a two-year-old, Jet Ski Lady competed against colts with mixed success in early 1991 before winning the Classic Oaks over one and a half miles at Epsom Downs Racecourse.
 Her winning margin of ten lengths was the second widest in the race's history and her starting price of 50/1 made her the equal longest-priced winner of the Oaks on records.
 She subsequently finished second in both the Irish Oaks at the Curragh and the Yorkshire Oaks at York.
 She was retired to stud after finishing unplaced in the Prix de l'Arc de Triomphe.
Dibidale (6 April 1971 – August 1975) was an Irish-bred, British-trained Thoroughbred racehorse.
 After one minor win in two races as a two-year-old, she emerged as arguably the best filly of her generation in the following year.
 She won the Cheshire Oaks by seven lengths and appeared a most unlucky loser when her saddle slipped in the closing stages of the Epsom Oaks.
 She then won the Irish Oaks by five lengths, beating the first three in the Epsom race and added a win in the Yorkshire Oaks before her season was ended by injury.
 She failed to win as a four-year-old and sustained a fatal injury in the Geoffrey Freer Stakes in August.
Sir Henry Richard Amherst Cecil (11 January 1943 – 11 June 2013) was a British flat racing horse trainer.
 He was widely regarded as one of the greatest trainers in history.
 Cecil was Champion Trainer 10 times and, as of June 2012, had trained 25 domestic Classic winners, comprising four winners of the Epsom Derby, eight winners of the Epsom Oaks, six winners of the 1,000 Guineas, three of the 2,000 Guineas and four winners of the St. Leger Stakes.
 His success in the Epsom Oaks and the 1,000 Guineas made him particularly renowned for his success with fillies.
 He was the Master Trainer at Royal Ascot, where he successfully trained 75 winners.
