1900s
1908 Norwegian Ole F. Bergan bends a juniper branch to support his soft rucksack, relieving the chafing wounds, while on a hunting trip. After he got home he made a prototype with tubular steel frame and leather straps.
1909 December 18, The invention was patented (number 20547) in 22 countries, and a Norwegian industrial adventure began.
1909 The "with" and "without" logo, portraying Bergan himself, smoking a pipe, was drawn by Ole F. Bergan's brother. This was of course a message about the advantages of the invention, but also that using the best equipment had something to do with mastering the outdoor life. It was used in the marketing for many decades.
