Ridinger was a German painter, engraver, draughtsman and publisher. He is considered one of the most famous German engravers of animals, particularly horses, hounds and hunting scenes.
He trained in Ulm with the painter Christoph Resch, and later studied under Johann Falch in Augsburg. He learned the art of engraving from Georg Philipp Rugendas. He spent three years in Regensburg: his coursing and visits to the riding school there proved decisive for his development.
Ridinger’s graphic works show the animals in characteristic movements and positions in a landscape environment. He later founded his own art publishing house in Augsburg. In 1759 he became the director of the Augsburg Stadtakademie.
