Letter from [Alan Archibald Campbell] Swinton, to The Editor, The Electrical Times Comments that a paragraph published under the heading 'Television', on 27 June 1929, is mysterious, having regard to a letter he published in Nature for 8 June 1929, enclosing a copy. Draws attention to the fact that the principle of Baird's transmitter was actually patented by Nipkow, a German, in 1884, before Baird was born. 27 June 1929
