Mervyn Pinfield
Mervyn Pinfield (born Reginald Mervyn Pinfield on 28 February 1912 in Evesham, Worcestershire, died 20 May 1966 in Islington[1][2]) was associate producer for Doctor Who from An Unearthly Child to The Romans. He also directed episodes of the Doctor Who television stories The Sensorites, (episodes 1-4) Planet of Giants (episodes 1 and 2) and all the episodes of The Space Museum.
Pinfield was originally supposed to direct Galaxy 4 and Mission to the Unknown, but fell ill while conducting pre-filming for the former at Ealing Studios. (TCH 5) He did direct some of the film inserts that were eventually used in Galaxy 4. (DWMSE 7)
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.
Out of all the people who worked on Doctor Who, his death was one of the earliest to occur over the long history of its production, less than three years after it had debuted.
Note
The production notes on the 2010 DVD release of The Space Museum give Pinfield's date of death as 20 August 1966.
