Johann Stephan Decker, a French painter, was born at Colmar in 1784. At the age of twenty he went to Paris, where he studied under David and Krapf, but at the end of seven years he returned to his native city. In 1821 he settled at Vienna, and was much employed at the court in teaching drawing and in the execution of miniatures and water-colour paintings. He died at Vienna in 1844.
