KOG has long been an important supplier to the American stained glass industry, including documented sales to Louis Comfort Tiffany, and in 1889, KOG won a gold medal at the Paris World Exposition for their multi-colored window glass. Among the important buildings fitted with glass from the manufacturer is the Chicago Public Library’s Central Library’s Book Delivery Room, which is now the Preston Bradley Hall of the Chicago Cultural Center.2
