| Title | Letter from [Alan Archibald Campbell] Swinton, to Sir Oliver Lodge |
| Creator | Swinton; Alan Archibald Campbell (1863-1930); British electrical engineer |
| Date | 19 March 1928 |
| Description | Acknowledges receipt of a previous letter and requests that Lodge sends a supplementary letter to Popular Wireless and mention his suggestions for the use of cathode rays in Television. Explains this is preferable for him as there is tendency on the continent to ascribe the first suggested use of cathode rays to a Russain Professor, Boris Rosing, who took out a patent in 1907. Discusses the details of this, listing other individuals who have made progress in the field. Comments there is a vast difference between a suggestion and a practical accomplishment, evidenced on page 4 of the paper he sent, drawing attention to the point that he never made any apparatus, at that his was only a suggestion. At the time, of his description in 1911, the cathode-ray oscillograph was in a very undeveloped and unmanageable condition but has since been greatly improved, but he believes that the working out of a successful cathode-ray method of Television will prove a very arduous, lengthy, and expensive work, and more suitable for one of the research departments of one of the great electric companies. Comments on having successfully repeated Lodge's experiment in his office, between the most distant points he could get, using a transmitter a Tesla coil and Leyden Jars, and as a receiver a coherer consisting of a heap of tintacks with a galvanometer. He then considered trying to send signals from his office in Victoria Street to his rooms in Jermyn Street, but the presence of many large buildings led him to the conclusion that the results would not be hopeful. |
