Ernst Sachs founded the "First Special Factory for Electrical Soldering Irons" in Berlin in 1921. He created the company´s title from the first letters of his own two names - and Ersa was born. With two hand-made prototypes of the famous H-1 electrical soldering iron which he just patented in Germany, Mr. Sachs visited the Leipzig Autumn Trade Fair. The Ersa H-1 was the first electrical soldering iron developed for volume production use that the world had ever seen. His products aroused a great deal of interest from within Germany and abroad and he received his first orders. Ernst Sachs managed his infant company with a great deal of personal involvement, inventive imagination and commercial foresight. He pushed ahead with continuous ongoing developments of the product range and expansion of production, showing a healthy readiness to take risks.
