Bobby Frankel, who rose from the streets of Brooklyn to become one of the most successful and respected trainers in the history of Thoroughbred racing, died early Monday morning at his home in Pacific Palisades, Calif., from complications of lymphoma. He was 68.\nFrankel had not been seen publicly in more than six months, since a recurrence of lymphoma, which he beat back about a decade ago, reappeared. In recent months, he only had contact with a handful of people, and he had dispersed a number of his horses. He had spent time shuttling between his home and Cedars-Sinai Hospital in Los Angeles while being treated. He left the hospital Saturday after expressing a desire to spend his final hours at home, according to a close friend.\nFor more than 40 years, Frankel was one of the top trainers in the sport. He began with claiming horses in New York, moved to California and continued to win at an eye-catching rate, then gradually transformed his barn into one that emphasized quality over quantity. He won at least one Grade 1 race every year from 1988 through this year. In 1995, he was inducted into racing's Hall of Fame.\n:: HALL OF FAME CAREER: (PDF)\n:: MORE: \nIn the nine years from 2000-2008, Frankel's barn won at least $10 million eight times. Last year, his final full year of training, Frankel's barn won 93 races and $11.7 million - placing him fourth in the nation in earnings - and his major wins last year included the Hollywood Gold Cup with a horse he owned, Mast Track. He won 11 Grade 1 races, more than any trainer in North America. His wins last year included the Champagne, Forego, Gamely, Go for Wand, Hollywood Turf Cup, Hopeful, Just a Game, Ogden Phipps, Personal Ensign, and Santa Anita Oaks. \nFrankel won 3,654 races from 17,657 starters and his horses earned $227,947,775, second all-time on the money list to D. Wayne Lukas.\nWith the exception of the Kentucky Derby, Frankel won just about every major event in racing. He won the Belmont Stakes with Empire Maker, twice won the Kentucky Oaks, and had six Breeders' Cup wins, most recently in last year's BC Filly and Mare Sprint with Ventura. His last major victory came with Champs Elysees in the Canadian International on Oct. 17. In recent months, Humberto Ascanio oversaw Frankel's horses in California, while Jose Cuevas and Ruben Loza took care of Frankel's New York-based runners, though Frankel was in touch with those men every day via telephone.\nFrankel was the Eclipse Award-winning trainer five times (1993 and 2000-2003), and he won 11 Eclipse Awards with 10 horses - Aldebaran, Bertrando, Ghostzapper, Ginger Punch, Intercontinental, Leroidesanimaux, Possibly Perfect, Ryafan, Squirtle Squirt, and Wandesta. In 2003, he won 25 Grade 1 races, a single-season world record.\nFrankel won 30 individual meet training titles, beginning in 1970 at Saratoga. He won 10 titles at Hollywood Park's spring meet, 6 at Santa Anita's Oak Tree meeting, 5 at Santa Anita's main winter meeting, 5 more at Del Mar, and 3 at Hollywood's fall meeting.\nHe was on top for so long that Julio Canani, another California-based trainer, nicknamed Frankel "Presidente" in admiration.\nFrankel was best known for his amazing success with turf runners. Frankel won 28 races worth at least $1 million, including grass races such as the Arlington Million (twice), Breeders' Cup Filly and Mare Turf (twice), Woodbine Mile (three times), and Japan Cup.\nHe won major turf races in bunches. Frankel won the Beverly D., Kilroe Mile, Shadwell Mile, and Turf Classic twice each; the Hollywood Derby, Manhattan, and San Juan Capistrano three times each; the Beverly Hills, Hollywood Turf Cup, and Oak Tree's Clement Hirsch four times each; the John Mabee and Yellow Ribbon fives times each; the Charles Whittingham Memorial six times, Eddie Read seven times, and the Gamely and Matriarch an amazing eight times apiece. \nHis other major stakes wins included the 2004 BC Classic with Horse of the Year Ghostzapper, the BC Distaff, and BC Sprint. He won the Pacific Classic a record six times; the Forego, Met Mile, and Woodward four times each; the Go for Wand, Hollywood Gold Cup, Las Virgenes, Ogden Phipps, Ruffian, and Strub three times each; the Malibu, Santa Anita Handicap, Santa Anita Oaks, Santa Maria, Suburban, and Whitney twice each; and also won the Acorn, Alabama, Alcibiades, Beldame, Blue Grass, Champagne, Coaching Club American Oaks, De Francis Dash, Donn, Florida Derby, Frizette, Haskell, Hopeful, Humana Distaff, Jockey Club Gold Cup, Kilroe Mile, Man o' War, Meadowlands Cup, Mother Goose, Personal Ensign, Santa Monica, Spinster, Stephen Foster, Sword Dancer, Test, Travers, United Nations, Vosburgh, and Wood Memorial.\nSeveral horses Frankel trained made their mark in the breeding shed, too, most notably the mare Toussaud, who produced Chester House, Empire Maker, and Honest Lady for Juddmonte Farms. He also trained Medaglia d'Oro, now better known as the sire of Rachel Alexandra.\n"Life's funny," Frankel said in 2000. "Sometimes things just happen, and they change your life completely. I wasn't born into this. I just followed my instincts and ended up where I am."\nFrankel was known as a bit of a grouch, one who complained long and loud when he saw something wrong. He could be playful and witty one moment, a pit bull the next. But his outspokenness was born of a sincere passion for the game, and his gruff exterior masked a man who would get choked up when misfortune befell one of his horses or his dogs. In 2007, Frankel missed the Breeders' Cup at Monmouth Park because his Australian shepherd dog Happy was near death. He would get emotional talking about the horses to whom he grew close, such as Exbourne or the filly Sightseek. He once complained about fans of the Detroit Red Wings throwing octopuses onto the ice. \n"I mean, they're living things," he said.\nHis employees were uncommonly loyal to him. Both Ascanio and Loza, for instance, worked for Frankel for more than 30 years.\nFrankel was keenly interested in politics; the television in his stable office was usually on CNN. He also loved baseball, and grew so close to Joe Torre that when Torre first took over as manager of the Los Angeles Dodgers, he lived in Frankel's Pacific Palisades house while Frankel was in New York.\nRobert Frankel was born on July 9, 1941 in New York to Merrill and Gertrude Frankel, who were in the catering business. Frankel first got into racing as a gambler, then found his way to the stable area, figuring a few hours walking hots in the morning was worth it to get a free pass to the afternoon's races.\nOne day in New York in the early 1960s he took $40 to the track, got on a roll by hitting the daily double, and by day's end made a successful $3,000 win bet on a 3-1 shot. He came home with $20,000.\n"I put the money on my mother's bed," he recalled in 2003. "She thought I had robbed a bank."\nEnamored of the sport, Frankel began training in 1966, and won his first race that year. His first major win came in the 1970 Suburban with Barometer, whom he had claimed for $15,000.\nTwo years later, Frankel relocated to California, and in his first season at Hollywood Park, in 1972, he set a single-season record at the spring meeting with 60 winners, mostly claimers. His first major clients were William and Marion Frankel, who were not related to him.\nWith the backing of Bert and Diana Firestone, Ed Gann, Jerry Moss, and Stavros Niarchos in the 1980s, Frankel gradually turned his barn into one filled with stakes runners. His success with European imports attracted the attention of owner Prince Khalid Abdullah of Saudi Arabia and his advisor, Dr. John Chandler, who boosted Frankel's stock significantly by turning over the United States-based horses of Juddmonte Farms.\nJuddmonte has won six Eclipse Awards as champion owner or breeder since being associated with Frankel.\nThough headquartered in California since 1972, Frankel for at least the past decade had a string based at Belmont Park and Saratoga from April through October, and he would usually spend half his year in California, half in New York, with brief stops in Kentucky for Keeneland in the spring or at Churchill Downs during Derby Week.\nFrankel is survived by his daughter, Bethenny, 38, who is a reality television celebrity on the show "Real Housewives of New York." Frankel was married twice, most recently in 2003 to Bonita Boniface. They divorced less than three years later, but she was with him during his final months. A memorial service for Frankel will be held Tuesday at 3 p.m. at Hillside Memorial Park, 6001 Centinela Ave., Los Angeles.
