How did an originally small Bavarian locksmith's shop develop into a globally active high-tech company that is technically one of the most innovative, largest and most renowned in its industry today?
After the death of his father-in-law, Georg Winzl, Hans Rosenberger took over his locksmith's shop in Tittmoning, Upper Bavaria, on January 1, 1958, and founded his own company: Hans Rosenberger Maschinenbau.

Mascot: a Pair of Storks on the Factory Chimney
In 1989, a pair of storks chose the Rosenberger factory chimney as their home for their offspring. After the wind destroyed the first attempt at nesting, a support frame was mounted by helicopter, which the storks willingly accepted.
Since then the nest has been inhabited for many years with numerous young birds starting their journey into the world from Fridolfing.
"Training is an Investment in the Future"
Hans Rosenberger Sr. would certainly not have put it that way, because he hated managerial phrases all his life. In the autumn of 1960 he hired three trainees to become machinists. Two of them stayed with Rosenberger their entire working life and, as masters and technicians, managed their own departments within the company for decades.
Incidentally, not only these two, but a significant number of other managers too. With the growing demands of the steadily growing company they took on increasingly demanding positions over time.
