„I soldered together my first modem when I was twelve years old,“ says Klaus Landefeld cheerfully. „That was particularly unusual in 1980, the pre-Internet era.“ At 16, the tinkerer turned his hobby into a profession and later studied electrical engineering. Landefeld is still an entrepreneur. But since 1997, he has also been involved in the big picture. Back then he became a board member at eco, the largest Internet industry association in Europe.
