Mystery Giver (foaled April 29, 1998 in Illinois) is a retired American Thoroughbred racehorse best known for winning three consecutive editions of the Fair Grounds Handicap at the Fair Grounds Race Course in New Orleans, Louisiana.
 Trained by longtime trainer Richard Scherer, Mystery Giver set the track record at the Fair Grounds in the Mervin H. Muniz Jr.
 Memorial Handicap.
 Scherer continues to race horses at the Fair Grounds during the winter, while spending the rest of the year in Chicago at Arlington Park and Hawthorne Race Course.
Frederick W. Ford (September 17, 1909 – July 26, 1986) was born in Bluefield WV.
 He was a graduate of West Virginia University, where he studied law ("Frederick W. Ford" B6).
 A Republican, he was appointed to the Federal Communications Commission in 1957, and after the chairman, John C. Doerfer, was forced to resign after allegations of conflict of interest, President Dwight D. Eisenhower named him to take over as Chairman of the FCC.
 Ford served in that role from March 15, 1960 to March 1, 1961.
 During his time as the Chairman, he was praised for being a man of integrity.
 One media critic called him "one of the most all-around competent commissioners ever to sit on the FCC" (Gould D25).
Major Frederick W. Barrett (20 June 1875 – 7 November 1949) was an English international polo player.
 He trained race horses for three British Monarchs George V, Edward VIII and George VI.
The "black spider" memos are letters and memos written by Charles, Prince of Wales, to British government ministers and politicians over the years.
 As the modern British monarch remains politically neutral by tradition, the letters are controversial because of Prince of Wales' position as the eldest child of the British monarch Queen Elizabeth II and heir apparent to the British throne.
The Frederick W. Panhorst Bridge, more commonly known as the Russian Gulch Bridge, is a reinforced concrete open-spandrel deck arch bridge on California State Highway 1, spanning Russian Gulch Creek in Russian Gulch State Park, Mendocino County, California, United States.
 It is named after Frederick W. Panhorst, who served as the Chief of the Bridge Section of the California Division of Highways from 1931 to 1960.
Horse Racing is an equestrian video game released by Mattel Electronics for its Intellivision video game console in 1980.
 Although primarily a sports video game, "Horse Racing" was actually assigned to the Gaming Network, due to its pari-mutuel betting for placing bets on the horses during the game; the game houses 8 virtual Thoroughbred race horses residing in the fictional "Rainbow Thoroughbred Stables" at a fictional western Kentucky race track called "Plympton Downs" (based loosely on long-time sportscaster/Intellivision sales personality George Plimpton).
 Each of the horses have differing racing abilities (front runner, pace keeper, come from behind, ...), and do vary from game time to game time (a horse with come from behind traits during one match may have front runner abilities during the next match).
 These horses are known by their colors (instead of their post position numbers—unlike in regular horse racing).
Edward VIII (Edward Albert Christian George Andrew Patrick David; 23 June 1894 – 28 May 1972) was King of the United Kingdom and the Dominions of the British Empire, and Emperor of India, from 20 January 1936 until his abdication on 11 December the same year.
The Frederick W. Lanchester Prize is an Institute for Operations Research and the Management Sciences prize (U.S. $5,000 cash prize and medallion) given for the best contribution to operations research and the management sciences published in English.
 It is named after Frederick W. Lanchester.
Kenneth L. "Ken" Ramsey (born 1935) and Sarah Kathern "Kitten" Ramsey (born February 5, 1939) are horse breeders and owners of Thoroughbred race horses.
 They have multiple graded stakes winners, three Breeders' Cup winners, and the Ramseys themselves have won multiple Eclipse Awards for outstanding owner and breeder.
 Ken and Sarah own Ramsey Farm, a 1,200 acre horse breeding operation in Nicholasville, Kentucky, and have raced horses at tracks throughout the United States.
 Many of their race horses have names incorporating the word "Kitten", Ken's nickname for Sarah Ramsey, used as the inspiration for the name of their leading stallion, Kitten's Joy, a successful racehorse in longer races on turf racetracks.
 When his style of racing proved unfashionable and outside breeders were reluctant to send mares to him, the Ramseys bought a herd of their own mares to breed and raced the progeny themselves, with considerable success, punctuated by Ken Ramsey personally leading most of his horses into the winner's circle after their races.
 To further promote the stallion, most of his offspring have "Kitten" in their names and, in some cases such as Breeders' Cup winners Bobby's Kitten and Stephanie's Kitten, the Ramseys honor friends or family members by incorporating their names as well.
The Native Diver Handicap is an American Grade III stakes race for Thoroughbred race horses run in late November at Del Mar Racetrack during its Fall Meet.
 (It was formerly held in early December at Hollywood Park Racetrack in Inglewood, California until that track's closing.)
 Set at a distance of 9 furlongs (one and one eighth mile] it’s open to horses three-years-old and up and currently offers a purse of $100,000 added.
