The company is named after Mr. Karl Söll, who founded the company in 1921. The correct pronunciation starts with "z" and rhymes with the English word "curl". To spell the name correctly "ö" and not "o" should be used, as these are actually different letters in the German alphabet. Unfortunately "ö" doesn't exist on English keyboards. The alternative spelling is "Soell", but this can be confusing for people who do not speak German. So for the English language website "Soll" has been used.
