Milton Toby, a longtime contributor to The Blood-Horse who wrote several books of racing history, died on Monday at his home in Georgetown of cancer, according to his family. Toby was 73. A native of Campbellsville, Ky., Toby graduated from the University of Kentucky and began his career as a general sports reporter in South Carolina, but he quickly migrated to Thoroughbred racing. He was hired by The Blood-Horse, which was then a weekly newsmagazine, in 1973, and spent the next 12 years at the publication, both as a reporter and a photographer. Toby pursued a variety of interests after his Blood-Horse tenure, including overseas photojournalism and law, though he remained connected to the Thoroughbred world throughout his life. He was the author of “Dancer’s Image, the Forgotten Story of the 1968 Kentucky Derby,” which was awarded the 2011 Dr. Tony Ryan Book Award, and “Taking Shergar,” which received a Book of the Year Award from the American Horse Publications in 2018. Toby’s 10th book, “Unnatural Ability, The History of Performance-Enhancing Drugs in Racing,” is set to be published by the University Press of Kentucky in August, according to his family. While teaching law beginning in 2003, Toby chaired the Central Kentucky Bar Association’s equine law division. He also sat on the board of American Horse Publications. By the beginning of this year, he had written “hundreds of articles,” his family said, including 125 “cover stories” for The Blood-Horse. Toby is survived by his wife, Roberta Dwyer. No services or visitation is planned, “although a gathering of remembrance may be announced later,” the family wrote.
