According to his longtime friend and attorney, Roger Licht, Nahem died of liver failure. The New York City native was 64.
There will be no formal funeral, Licht said, but a memorial is planned at Nahem’s home on Nov. 19.
Nahem raced Bertrando, who would become the champion older male of 1993 after finishing second in the Breeders' Cup Classic (gr. I), in partnership with John Naify's 505 Farms and Gus Headley. He continued to own a major interest in Bertrando, who stands at Martin and Pam Wygod's River Edge Farm. His horse Hugh Hefner was a son of Bertrando. Nahem also campaigned the mare Queenie Belle, whom he bred in partnership, with 505 Farms.
Nahem raced under the nom de course King Edward Racing Stable. The grade I winner Bilo, a 7-year-old Bertrando gelding owned and bred by Nahem, is entered in the Dodge/Don Valpredo California Cup Sprint Nov. 3.
A former antiques and art dealer, he is survived by a son, Jarrett.
