futurist and prolific genius -> Artur Fischer
Probably the inventor who had the most impact on my life. Best known the wall plug (near weekly use), metal implants after bone fractures (being a goalie was dangerous), synchronized flash for cameras (all these family photos), and .... most important for me fischertechnik which allowed kids to build nice technical stuff, way better than LEGO.
