After World War 2, he worked as a journalist for German broadcaster NDR, covering political and economic issues, and later took over sport coordination at ARD in Munich, where he remained until his retirement in 1987.
One of the highlights of his career in television was doing the live commentary on the equestrian competitions at the 1956 Olympic Games in Stockholm. From then on he was present at nearly all the major equestrian events, including one of the biggest and most popular horse shows in the world, CHIO Aachen in Germany.
For almost 60 years, "the voice of equestrian sport" continued to commentate at events and speak at seminars and congresses. He wrote several books, including "The Beauty of the Horse", "The Imperial Horse: The Saga of the Lipizzaners", "Horses and Riding (Questions answered)", "Birth of a Foal", and "A Foal Is Born". He also made a film on horses.
Hans-Heinrich Isenbart's funeral was held on January 10 in the Niedersachsenhalle indoor arena in Verden in Germany where, during his long career, he had been a Master of Ceremony at many gala evenings and had commentated numerous horse shows. Nearly 700 mourners attended the emotional service.
Hans-Heinrich Isenbart will always be remembered for his great eloquence, but also for his life-long dedication to horse welfare. His famous words at the end of every single broadcast were, "Und vergessen Sie die Pferde nicht!" (And don't forget the horses!)
