"der Kindermacher", Herzog von Kleve, Graf von Mark) (13 April 1458 – 15 March 1521) was a son of John I, Duke of Cleves and Elizabeth of Nevers.

He was called "The Babymaker" as he had fathered sixty-three illegitimate children[2] prior to his marriage with Mathilde of Hesse in 1489.

Pope Innocent VIII awarded John the Golden Rose of Virtue on 15 April 1489.

This is remarkable in light of the fact that John, with his alleged 63 illegitimate children, had the dubious reputation of being a "child maker".

From then on, John called himself "Johann von Kleve, Count of La Marck and Katzenelnbogen".
