Carl Richard Nyberg was a specialist in soldering, but he felt that the soldering technology available in the 1880´s could be greatly improved. He was determined to find a heating source that was more efficient. After much experimentation he succeeded in finding a solution, and in 1882 he made the first prototype of a soldering blowtorch for which he also obtained a patent.

That same year the future industrialist, Max Sievert, opened the doors of a machinery business in Stockholm that would form the foundation of a major company. When the paths of Nyberg and Sievert later crossed, they formed a partnership that was uncommonly fruitful. Nyberg manufactured blowtorches, and Sievert sold them throughout the world. A successful business was launched.

Since 2003, Sievert is a member of the Rothenberger group of companies: www.rothenberger.com
