1891 Tretorn was founded by Johan Dunker in Helsingborg, Sweden, setting the stage for one of the most enduring success stories born from the late industrial revolution.
Soon after the company's beginning, Johan Dunker's son, Henry, is hired at the age of 21 as the company’s only salesman to get the infant company off the ground. Later, he inherits the company and builds the company Tretorn, as we know it today.
Dunker’s company produces 39,000 pairs of galoshes in 1892. Just two years later, the number rises to 206,000.
