Frank Fenton was the designer and decorator. Between 1905 to 1920, the designs made there were heavily influenced by two other glass companies, Tiffany and Steuben. But the many different colors were the work of Jacob Rosenthal, a famous glass chemist who is known for developing chocolate and golden agate glass. Towards the end of 1907, the Fenton brothers were the first to introduce carnival glass, which would later become a popular collector's item.
