Restoration of this historic stained glass window from the Oidtmann Glass and Mosaic Studio. The bottom panel has the signature of the maker, Dr. Heinrich Oidtmann, a medical doctor and stained glass scholar, who founded the studio in Germany in 1857. Dr. Oidtmann was inspired to study glass while working with glass slides. His studio grew into a major business with 100 employees.
