The Transit Telescope became an excellent instrument, but not for the purpose of which we built it. I think the time... I'm now talking about 1949, and I had a telephone call from FC Williams, who was then developing his computers in Manchester, and whom I'd worked with during the war, and he asked me if I remembered Hanbury Brown. Well, of course, I remembered Hanbury Brown, and he said, 'Well, Hanbury Brown wants to come back', and... he had left the organisation after the war, and was then working with Watson Watt on a commercial development. But he wanted to come back and complete his studies in the university, which he had left in 1938, in order to help EG Bowen with the development of radar. It was airborne interception. And FC Williams kindly said that he thought that Hanbury Brown might be more useful and more interested in what I was doing than what he was doing on his computers. I mentioned this to Blackett, and Blackett was very keen to supply me with students when he saw that we were beginning to developed, and we obtained for Hanbury Brown an ICI Fellowship.

So it was in that way that Hanbury Brown came to me, and his presence in the next few years was absolutely vital to the development of Jodrell. He came to me, and I suggested... I showed him the Transit Telescope, I showed him the results, which had been obtained by Victor Hughes, and I said, 'Would he like to take over that instrument and use it for the study of the cosmic radiation from space?' He did so, and he acquired another research student, Cyril Hazard, and together they started work on equipping this Transit Telescope with a suitable radio receiver. Hanbury Brown was then one of really one of the world's experts on electronics, and so the building of sensitive receivers was of no problem to him whatsoever, and he produced an excellent receiver. I think we were then working on a wavelength of about 160 megahertz or 200 megahertz, in that order, anyhow.
