Electronic TelevisionIn 1939 mechanical systems in public communications were almost exclusively in use, yet pioneers were experimenting with electronic television. George Eckhardt has written an easily understood yet technically comprehensive work describing the operations of the Farnsworth and RCA laboratories and containing fascinating illustrations of the first television stations and receivers used in television experimentation during the mid-1930s. Upon publication of this work, New Technical Books reported: "The art of writing on highly technical subjects in a non-technical light is extremely difficult and the author is to be given credit for a great accomplishment". |
