Karger's approach to making pictures was similar to contemporary
Thomas H. Ince. Both died relatively young, but where Ince is remembered for his streamlined productions and circumstances surrounding his death, Karger is relatively forgotten today. Karger was a founder of
Rolfe Photoplays in New York but later worked primarily at the
Metro Pictures studios and was later a personal assistant to
Rudolph Valentino. Karger died of heart disease while on a train between New York and
Fort Wayne, Indiana. His son Fred Karger (1916–1979) was a voice coach at
Columbia Pictures and was the fourth and final husband of actress
Jane Wyman after her marriage to
Ronald Reagan ended. ==Selected filmography==
