[Released June 18, 1930. Dated June 6, 1930]
I SEND cordial greetings to those present at the "American Hour" of the World Power Conference in Berlin. The imagination is stirred by the ever-widening field of knowledge and its practical application in the multiplying instruments of service to mankind. Civilized society depends in ever increasing degree upon the spirit of inquiry and the utilization of scientific truth. Those who serve this cause serve the best interests of the race.
HERBERT HOOVER

The World Power Conference, the second of its kind, met in Berlin from June 16 to June 25, 1930. Involved were some 4,500 delegates from 50 nations, who participated in 34 group meetings and listened to approximately 500 technical papers dealing with electrical power development and other forms of energy. The American delegation was headed by Oscar C. Merrill, former Executive Secretary of the Federal Power Commission.
