In 1905, both Goldberg and Ullman moved to Technische Hochschule in Berlin. Goldbergs research, along with that of the Ullmann-Goldberg collaborative, was also a part of Germanys synthetic dye industry. Their research helped with the creation of the synthetic alizarin industry, or the process of replacing natural dye obtained from madder. In 1909, Goldberg also collaborated with Hermann Friedman to review German patents under BASF (Badische Anilin und Soda Fabrik) and Bayer & Co. Farbenfabriken, providing notes on preparation for 114 dyes.
