Painter Alfred Krupa (1915-1989) was the very first man who invented the suitcase with wheels in the early 1950's

According to the UNTWO (World Tourism Organization) 1.2 billion people made an international trip in 2015 , and it is predicted that it will rise to 1.8 billion world travelers in 2025. Suitcase with wheels is known to all those who traveled but the real inventor of it is not known to everyone.Many journalists reported that in 1970, Bernard Sadow, then the owner of the American company U.S. Luggage (now part of the Briggs & Riley TRAVELWARE) invented and patented in 1972 first suitcase with wheels and so changed the world of travel.It is true is that Bernard Sadow was the one who patented with success suitcase with wheels but not the first man who invented it and use it in daily travelling. Those are, of course, two separate things.The fact of the history is that the painter Alfred Krupa was the very first man who invented the suitcase with wheels sometime before or in 1954 (in period 1950-1954). And that is only one among his popular creations from early 1950's.
