DINSDALE (ALFRED)
Footnotes
FIRST EDITION OF THE FIRST BOOK IN ENGLISH ON TELEVISION. Dinsdale discusses the technical challenges faced by early experimenters, but focuses primarily on the work of Scottish engineer John Logie Baird, the first person to produce televised pictures of objects in motion. In February 1924, Baird produced the first television image in outline, and in April 1925 he transmitted the first pictures between two televisions. By the following October, Baird had succeeded in transmitting images with gradations of light and shade, and on 27th January 1926, he successfully transmitted recognizable human faces between two rooms by television. Of Baird's early experiments, Dinsdale writes: "Baird's weird apparatus - old bicycle sprockets, biscuit tins, cardboard discs and bullseye lenses, all tied together with sealing wax and string - failed to impress those who were accustomed to the shining brass and exquisite mechanism of the instrument maker. The importance of the demonstration was, however, realized by the scientific world..." (p 49). Although he did not succeed in producing a viable system of television, Baird paved the way for future technical development.
