Sievert's history

Where it all began

Carl Richard Nyberg, a soldering specialist, knew that the soldering techniques in the 1880’s left a lot to be desired. He was determined to find a heat source that would streamline the work. In 1881, he managed to craft the first soldering blowtorch which he also secured a patent for. 

The same year, German industrialist Max Sievert opened the doors to his machinery store in Stockholm which later formed the basis for an industrial conglomerate. When Nyberg and Sievert crossed paths in 1886, a successful collaboration was formed. Nyberg manufactured the blowtorches and Sievert sold them worldwide. 

For more than 140 years, SIEVERT has been a household name and associated with high-quality heating tools and cooking stoves for professional use. Our history and legacy is dear to us. Today, we carry that legacy in everything we do. Whether it’s developing a new innovative heating tool, our relationship with our customers or suppliers, we always strive to deliver original professional excellence.

Carl Richard Nyberg

From poverty to success – the inventor who lit the spark!

Despite a childhood marked by poverty and hard labour, Carl Richard Nyberg never let adversity stop him. With a passion for technology and ingenuity, he created and patented the revolutionary blowtorch in 1881, an innovation that changed crafts and industry worldwide. 

He was also an aviation pioneer, far ahead of his time, and designed both steam-powered flying machines, a flying boat and Sweden's first wind tunnel. With persistence, skill and an unwavering faith in the future, he built a successful business and became one of Sweden's most versatile innovators. From a simple workshop to international success – Carl Richard Nyberg is proof that innovation and hard work can change the world! 

Quite the character

It's well documented that Nyberg was way ahead of his time regarding his care for his employees and their well-being. At the same time, he had no regard for his competitors. He once got arrested for publicly blowing up his competitors’ blowlamps in the town square in an attempt to prove that his blowtorches were the safest. 

Max Sievert

The entrepreneur who ignited Swedish industry! 

With a keen business instinct and drive for innovation, Max Sievert built bridges between Sweden and the international market. Originally hailing from Germany, he started as a salesman of tools and machines but quickly saw the opportunities in new technology. Through collaborations with pioneers such as L M Ericsson, the Nobel brothers and Carl Richard Nyberg, he became a key player in the development of the rapidly growing Swedish industrialization. 

His entrepreneurship extended far – from machines and luminaires to electronics and technical innovations. With his drive and vision, he laid the foundation for several successful industries and contributed to Sweden's place as a technological powerhouse. A true pioneer who saw opportunities where others saw obstacles. 

A cable guy

Max Sievert, who was a jack of many trades, was also extremely successful in the early cable and telephony industry. Sievert’s Kabelverk became one of Europe's largest cable manufacturers and largely electrified the Nordic markets with high-voltage cables, as well as building the cable network for telephony. This also led him and L M Ericsson to become the best of friends.
