Hartwig Steenken

Hartwig Steenken (23 July 1941 – 10 January 1978) was a West German show jumper. He was born in Twistringen, and raised on his father's farm in Bowrede near Hoya in Lower Saxony. He won silver at the 1975 European Championships, and decided not to compete in the 1976 Olympics as he had no horse good enough to win; his earlier mount, Simona, being too old.

On 1 July 1977, Steenken broke the FEI's rules on amateurism by signing a sponsorship deal with Campari. Twelve days later, he sustained serious head injuries as a passenger in a car which crashed into a wall returning from an amateur football match in which he had played. He fell into a coma and died six months later in Hanover.
