All the stained glass windows were removed from Dahlgren Chapel, the Catholic worship center at Georgetown University, Washington, D.C. Photographic reproductions (SKRIM) were hung in front of each window so the chapel could continue to be used during the year long restoration project. The windows were transported to the New Jersey studio where they were completely de-leaded, cleaned, and re-leaded, ready for reinstallation. New protection glass was installed on the exterior. The high quality painted windows were made by Mayer of Munich, Germany in the early 20th century.
