a real world point of view
Mervyn Pinfield (28 February 1912-20 May 1966) was associate producer for Doctor Who from An Unearthly Child to The Romans. He also directed the Doctor Who stories The Sensorites, Planet of Giants and The Space Museum. His non-Doctor Who directing credits include The Monsters, The Franchise Affair and Compact.
Before joining the BBC early in the 1950s to work on live drama at Alexandra Palace, he spent over four years in 'weekly rep' as Director/Theatre Manager at the Royalty Theatre, Morecambe. Pinfield was the inventor of an early type of Teleprompter, or Autocue, which he called the Piniprompter.
Note: The Production Notes on the 2010 DVD release of The Space Museum give Pinfield's date of death as 20 August 1966.
