Artist. Frei was a noted stained glass artist and designer of the mosaics in the St. Louis Cathedral. A native of Bavaria, he learned painting in the Munich Academy of Arts. His earliest work in St. Louis was in this field. After founding his art glass business, he executed many orders (mostly for Catholic churches), but many were also for Protestant churches, other organizations and private homes (including the August Busch home on Grant’s Farm.) He worked on the St. Louis Cathedral mosaic commission with his son for many years. It is one of the largest single examples of mosaic in the world and cost more than $1,000,000 in the 1930s.
