He became the first full time chairman of radiology at the University of Minnesota in 1933 at the age of 37, a position he held until 1957. He then moved to California, becoming the executive director of the Cedars-Sinai Medical Center until 1963. He then became professor of radiology at the University of California, Los Angeles at the age of 67, and directed the postgraduate radiology training.
