Ralph Bown was well known for his introduction of the transistor at the first press conference at Bell Labs. His article discusses how far transoceanic radio use has come: "Ten years have elapsed since the opening to public use on January 7, 1927, of the first long distance radio telephone circuit. This form of intercontinental communication has now come into practical business and social use. A network of radio circuits interconnects nearly all the land wire telephone systems of the world. The art has passed through the pioneering stage and is well into a period of growth." The Norton article has over 185 citations as of this writing and covers "Completely general formulas are given for computing at any point above a plane earth of finite conductivity the vector electric field for a source which may be a combination of vertical and horizontal electric dipoles or a loop antenna with its axis parallel or perpendicular to the earth."
