Adolph Mogavero, a respected horseman, official and member of the Show Jumping Hall of Fame, died Aug. 25 in Sarasota, Fla. He was 89.

Mr. Mogavero was born just outside of Boston, Mass. He lived down the road from a horse farm and would regularly stop on the way home, sit on the fence and watch the riders. When he was 9 years old, the trainer asked him if he would like to begin riding, an offer he promptly accepted.
