After early training in his father's workshop, Erhard Brepohl studied at the College of Applied Arts in Leipzig where in 1953 he received his Masters level status. He went on to take additional degrees in mechanical engineering and industrial design and taught for many years at the College of Applied Arts in Heiligendamm. Combining his love of history with his knowledge of goldsmithing, Brepohl translated the famous 12th century manuscript of Theophilus Presbyter, a task that required him to first learn Latin. The results of his scholarship were published as a book in 1987; this served as his dissertation and earned him the title of Doctor of Philosophy.
The Theory and Practice of Goldsmithing, published in 1961, would go on to sell over 100,000 copies in Germany and Russia. He has written five other books, including Artistic Enameling in 1979 (translated in Russian and Hungarian) and Cutting and Setting Precious Stones in 1988.
