Foreword

John R. Pierce
Executive Director, Research,
Communications Principles and Communications Systems
Bell Telephone Laboratories

When I first talked about the possibilities and advantages of communicationssatellites to the Princeton Section of the Institute of Radio Engineerson the evening of October 14, 1954, I was diligent in my analysis andenthusiastic in my presentation but, I must confess, a little skeptical as towhether or not anything would come of the idea.

Still, others and I at Bell Laboratories remained interested, and, after thelaunching of Sputnik I on November 3, 1957, and of Explorer I on January31, 1958, we worked actively toward satellite communications experiments.This led to our work with Echo I (launched August 12, 1960) and finallyto the launching on July 10, 1962, of Telstar I—that satellite which became,in the words of Queen Elizabeth, “the invisible focus of a millioneyes.”

This work on communications satellites has been a grand explorationand opening up of a hitherto dark continent of science and technology. Mycourageous friends at Bell Laboratories encountered therein surprisingdifficulties and perplexing problems which I had never dreamed of, andthese intrepid and indefatigable adventurers grappled with them and masteredthem all.

Now you, who have in your own homes seen pictures transmitted acrossthe ocean by satellite, can learn first hand from the men who worked onhard and varied technical problems just what these problems were andhow they were solved. And, by reading you can find out what sort ofknowledge, training, and habits you yourself will need if you wish someday to adventure into those undiscovered or unexplored fields of technologywhich will be new and exciting when Telstar has become old hat.
