De Jeney moved to St. Louis, Missouri, in part due to his passion for fishing and outdoor activities.
He was a highly regarded portrait painter and was also known for creating replicas of famous oil paintings that rivaled the originals.
In 1976, De Jeney moved to Washington, D.C., after receiving a special honor to create commissioned copies of historical paintings.
[1] An unknown number of De Jeney originals and replicas remain in circulation, mostly in the United States and Europe.
De Jeney was known mostly for oil on canvas and his replicas of other paintings are most frequently found to be remarkably similar to those of Rembrandt.
