Biographical / Historical

Leo Moser was the son of Ludwig Moser, founder of Ludwig Moser & Söhne. Born in 1879, Leo Moser worked in the family glass business, assuming the technical directorship in 1908 and artistic directorship in 1916. Leo Moser is known for both for his design work and his use of rare earth metals in glass production to achieve more variety in the color of Moser glass.

The worldwide economic crisis of the late 1920s and 1930s hit the decorative glass industry hard, and by 1932 Leo Moser sold all of his shares of the Moser firm. He left the company and worked for other glass firms, including Josef Inwald and Cristalleries de Saint Louis. In the early 1940s, he immigrated to the United States and appears to have sought to establish himself in American glass manufacturing. Leo Moser died in New York in 1974.

Roger E. Ritter was born in Prague in 1896. From 1929 to 1938, he served as the director of the Bohemia - Moser retail store in Prague. After the Sudetenland Crisis in 1938, he immigrated to the United States. He opened an independent Bohemia - Moser store in New York City in 1938. There is some evidence that he intended to return to Prague and help restore the Bohemian glass industry after World War II, but Ritter remained in New York, working as a glass and porcelain buyer for R. H. Macy & Co. Ritter died in Honolulu, Hawaii in 1985.
