Pioneering in Talking Pictures

To pioneer has always been with me an obsession. Perhaps the yearning to explore new fields was an inheritance from colonial ancestors. Vanished geographical frontiers still left far vaster regions in science and technology to explore. When early wireless began to be a bit crowded the radio telephone field, then scarcely a dream even among communication engineers, beckoned me irresistibly. This primitive beginning of the radio broadcast, in 1908, logically necessitated the development of the electronic amplifier from the audion detector tube (Fig. 1); and thus again I managed to escape the crowd. And when, in 1912, this amplifier proved to be also an oscillator, a boundless ocean disclosing alluring archipelagoes of practical application was opened to scientific research.
