Sidney Chapman, realized that the peaceful post war time was a good occasion to start a strong, internationally coordinated, scientific program for a new global geophysical endeav-our. The time was right also due to the availabil-ity of new technologies: rockets, radar and nu-merous other geophysical techniques which had been developed during the war. Later on several other scientists from all over the world agreed to start this enterprise and, supported by the experience of the previous two Internation-al Polar Years, IPYs, in 1882/83 and in 1932/33, agreed that the time was right for a new coordinated scientific effort (Buedeler, 1957; Gerson, 1958). Although the second IPY had occurred less than 50 years earlier, a reprisal after 25 years was motivated by the an-ticipated sunspot maximum of the 11-yr solar cycle in 1957-1958.
