John A. Bell III, the prominent Thoroughbred owner-breeder who founded Jonabell Farm and was involved in the American Horse Council, has died at 88.

Bell died Wednesday evening at St. Joseph Hospital Hospice in Lexington after battling pulmonary fibrosis.

He sold Jonabell Farm, best known as the final home and resting place of Triple Crown winner Affirmed, in 2001 to Sheikh Mohammed.

Raised on a farm near Pittsburgh, Bell used the proceeds from the sale of a litter of pigs to buy his first mare. He founded Jonabell Farm in Fayette County in 1954.
