Ken Draper for many years was the curator of the Projected Picture Trust when they had a cinema and museum at Bletchley Park, Milton Keynes. Ken had a long career in cinema and projection, including being one of the few to have run Cinerama in the 1950s. A number of years ago in did an interview for the Trusts magazine, Rewind. Our friends at in70mm reproduced the interview as a tribute to Ken.
