From a one-man business to a global player: it all began in the market town of Pettenbach, where company founder Günter Fronius earned a living as a repair and maintenance man in 1945. Then came the idea that got the ball rolling: the trained electrical engineer developed a battery charger for cars. “I’ll build you a device that you can connect to the grid to charge the battery,” said Günter Fronius. Over the years the product range has expanded many times over. • 1945: 1 employee • 1980: 250 employees • 2009: 2,700 employees • 2020: 5,660 employees • 2023: more than employees • • • •
