Frans Lidqvist, a mechanic in an engine factory in Stockholm Sweden, saw the handheld blow torch, and thought of turning the flame upward, and using it as a portable stove. He got a Swedish patent and started making them for friends and relatives. Soon he partnered with Johan Svensson, who owed a small workshop, and they started a company to make the stoves, which were sold under the name Primus in 1892. They soon sold the global marketing rights, and the Primus stove went worldwide.
