Hannes Alfvén (1908 - 1995)

As a child at school in the remote Swedish town of Norrköping, Alfvén was a member of the school's radio club. There were no nearby radio stations, and Alfvén was thrilled when, on tuning the receiver that he had built, he heard faint notes of music coming from a station in Aberdeen!
