Sherwood C. Chillingworth, a longtime director and executive vice president of the Oak Tree Racing Association, died Oct. 8 at age 93.
A native of Honolulu, Chillingworth, known affectionately as "Chilly" to all who knew him, was named an Oak Tree director in 1989 and assumed the title of executive vice president in 1993. A tireless advocate for the many causes the not-for-profit Oak Tree Racing Association funded since its inception at Santa Anita Park in October 1969, Chillingworth was a beloved figure in California racing.

"He was a great man who was a very big part of the Oak Tree Racing Association for many years," said Hall of Fame trainer and fellow Oak Tree Board member Richard Mandella. "He lived a full life, and from what I knew, he loved every minute of it. He had a great sense of humor, he loved to bet, and he loved our game."
Although still active in funding various charitable causes, the Oak Tree Racing Association, which conducted its final fall meeting at Santa Anita in 2009, operated for one year at Hollywood Park in 2010 and then conducted fall meetings at the Alameda County Fair Grounds in Pleasanton through 2018. 
A former real estate developer, Chillingworth, who served as vice chairman and CEO of Santa Anita Realty Enterprises from 1994-96, had a passion for horses and horse racing. He owned and raced Thoroughbreds dating to the early 1970s under the nom de course Paniolo Ranch.
It was in Thoroughbred partnerships, however, that he experienced considerable success. He owned percentages of grade 1 winners Swing Till Dawn (1983 Strub Stakes and Widener Handicap), Yashgan (1985 Oak Tree Invitational and 1986 San Gabriel Handicap), Forzando (1985 Metropolitan Handicap), and Valley Victory (1986 Coaching Club American Oaks).
"He was a first-class guy," said Hall of Fame conditioner Ron McAnally, whose legendary gelding John Henry won three straight runnings of the Oak Tree Invitational (G1T) in the early 1980s. "Doc Robbins (original Oak Tree Director and John Henry's attending veterinarian) admired him so much, and was so appreciative of everything he meant to Oak Tree and our racing here. 'Chilly' was good for the horses, and he was good for the business."
A consummate gentleman and tireless consensus-builder, Chillingworth was also a past steward of the Jockey Club, secretary of the Board of the Thoroughbred Racing Associations, director of the Thoroughbred Racing and Protective Bureau, and member of the Equibase Management Committee.

"'Chilly' was one of the kindest and most gracious executives in racing," said George Haines, former Santa Anita general manager. "He treated the employees with great respect and was universally loved by all. His wit and humor will be missed but not forgotten."
Chillingworth, who resided at Santa Anita Park with his wife, Sandra, is also survived by four sons, two daughters, and several grandchildren.
