Marcel Haëntjens
Marcel Haëntjens was a French croquet player and equestrian. He competed at the 1900 Summer Olympics in both croquet and equestrian. In croquet he competed in both the one ball singles and the two ball singles and did not finish in either. In equestrian he did not finish in either the high jump or the mixed jumping. His final event was the hacks and hunter combined. He finished fourth in this event which, until recent years, was not considered an official Olympic event by the International Olympic Committee.
