I met David in Munich, where he cut a very urbane figure around the village.

Yet there were few grittier competitors in the pool, as evidenced by his gold medal in the Montreal 200 breaststroke. With his career peak seemingly behind him after relinquishing the world record he’d set three years earlier, David totally dominated his Montreal final with a quantum drop in the world mark.

When I was doing some “scholarship tourism” in 1973 and moping around the University of Miami campus, he was enormously generous and helpful with his time.

David was both trendsetter and hero.
