Add to ORKGIn 1929 members of the United Dental Laboratories were photographed by Charles Bretzman. The customer card listed the company at 624 Bankers Trust Building in Indianapolis and a Mr. Nachbar was the contact person. The city directory listed the group at the same address with O. Adrian Nachbar as the secretary treasurer of the organization. Census records for 1930 show Mr. Nachbar was 36 years old, his wife Ruth was 31, they lived at 5627 Julian Avenue, and he was still working at the organization. He is probably one of the individuals in this group photo.This image is a preservation copy made from an unstable original nitrate negative. The image is part of Series III
