Franz Grosz was an artist who worked in a variety of media, including glass. He did not work for a glass firm, but purchased blanks, and sold them through his own firm, and through his agent Mary Ryan. A brief look at the books on Tiffin glass, who supplied his blanks, was not productive. Searching the Internet, especially Ebay, will yield some additional examples of his work. Dates of the firm have not been determined. The Rakow Library has the 1951 Red Book, issued by the periodical China, Glass and Decorative Accessories, which includes a listing for the firm in Elmhurst, NY, owned by Joseph F. Grosz and Robert Bodkin: “decorators of glass for giftware and decorative architectural purposes”. The next directory the Rakow Library has is from 1955, which does not list the firm.

I have attached a bibliography with suggested sources on Franz Grosz. If you would like to borrow copies of library items, please contact your local library.
