Letter from [Alan Archibald Campbell] Swinton, to The Editor, The Electrical Review Comments there is no mention of “La Television Electrique” by A. Dauvillier in the book “The A. B. C. of Television”, by Raymond Francis Yates. Explains that Dauvillier has done much work in experimental television and his historical account is complete, instructive, and impartial. Adds that Sir Oliver Lodge supports Dauvillier’s and his own view that the required rapidity of the functioning apparatus in television can only be obtained using cathode rays. 2 November 1929
