Hans Gruyters was a Dutch criminal. In the 1950s, he was a car salesman in the Dutch province of North Brabant. His nickname was The Black Rider, because he once appeared completely dressed in black at a party.
In popular culture
• Erik Vink (a Dutch journalist and playwright) wrote a play called De Zwarte Ruiter (The Black Rider) about Gruyters, which has been performed by a number of small theater groups. This play should not be confused with De Zwarte Ruiter (The Black Rider) - a film by Wim Verstappen. • The Ottawa-based band, Wise, Young and King made Hans Gruyters the subject of their song, The Black Rider. ==References==
