Together with his father-in-law, John E Johnsson started Trangia, a company that would eventually become the leading provider of outdoor stoves in Sweden. In 1951, they launched the first prototype of the Trangia stove; a complete cooking system with a burner, pot and windshield. Trangia has since become one of the leading outdoor industry brands, both in Sweden and around the world. Generations of scouts, mountain hikers and outdoor enthusiasts have cooked their meals on a Trangia stove, still made in the village of Trångsviken, in northern Sweden.
