My first book, a school prize, I think. Introducing Astronomy by J B Sidgwick. It was that book, along with growing up at the start of the space race, that got me hooked. After that Starlight Nights and, of course, Norton’s. Particularly the earlier ones that opened flat. The little paperback Artificial Satellites by Michael Ovenden, bought on holiday in 1960 on the Isle of Wight for 5 shillings was also a great read.
