ROBERT MILLIKAN AND HIS ROLE IN THE BIRTH OF MODERN RADIO TUBES
Abstract and keywords
Abstract (English):
The article focuses on the work of Harold Wilson, Robert Millikan and his students, in particular, Louis Begeman and Harvey Fletcher on determining the magnitude of an elementary electric charge. Attention is drawn to the priority of authorship in the publications of R. Millikan and H. Fletcher based on the results of joint research. A controversy was noted around the results of Millikan’s experiments to determine the electric charge of an electron. The situation with R. Millikan’s recommendation of his student Harold de Forest Arnold to the WECo research group for the development of a telephone electronic repeater is described.

Keywords:
electron, electron charge, Harold Wilson, Robert Millikan, Louis Begeman, Harvey Fletcher, Harold de Forest Arnold
