Former Doctor Who producer Derrick Sherwin, the man responsible for creating UNIT, has died at the age of 82.

Derrick Sherwin worked on Doctor Who in many capacities, writing scripts, producing the series for the transition between the second and third Doctor, and even appearing in one scene, playing a Car Park Attendant in the 1970 story Spearhead from Space. His most lasting legacy was creating the United Nations Intelligence Taskforce or UNIT for the 1968 story The Invasion. UNIT, helmed by Brigadier Lethbridge-Stewart, was an essential component for the Third Doctor's tenure, with its influence reaching as far as the Twelfth Doctor.

Sherwin was born in 1936 in the Buckinghamshire town of High Wycombe, just west of London. His early work was in the theatre, but he quickly moved into television appearing in the 1958 show Duty Bound. Over the next ten years, he had a steady series of small roles appearing in dramas such as Here Lies Miss Sabry, The Edgar Wallace Mystery Theatre, United! and Armchair Theatre.

His first contact with Doctor Who came when he joined as Assistant Script Editor to help the incumbent Peter Bryant who was preparing to take over as producer. It was a baptism of fire as he was immediately charged with rescuing a number of scripts which were not ready for production. He told Doctor Who Magazine. He took over as Script Editor for the 1968 story The Dominators and later that year had the chance to write his own story from scratch. The result was The Invasion, the Cybermen story that set up the pattern for the series for much of the next five years. Sherwin felt the series had become too fantastical, with different monsters every week. He wanted to give the series a more grounded approach and saw as his inspiration the 1950's Quatermass stories. To help achieve that he took a character created for the story The Web of Fear, Colonel Lethbridge-Stewart, promoted him to Brigadier, and created UNIT around him. Sherwin took over of producer for the last Patrick Troughton story, The War Games and was responsible for casting the third Doctor Jon Pertwee and overseeing the series move from Black and White to Colour. He left the series after Spearhead in Space

He moved onto produce the series Paul Temple and later The Man Outside and Perils of Pendragon

In the 1980's, when Doctor Who was under threat of cancellation from the BBC he offered to buy the franchise from the BBC and produce it independently. Derrick Sherwin died on the 17th October after a long illness.

Doctor Who on Twitch

Graham Strong, the man responsible for the survival of many high-quality audio recordings of missing Doctor Who episodes, has died at the age of 69.

Graham Strong was a 14-year-old schoolboy when Doctor Who began in 1963. A keen electronics student, his hobby included building valve and transistor radios, as well as repairing televisions for neighbours. He was the proud owner of a second-hand Reel to reel tape machine and decided to use this to preserve the audio of this exciting new serial.

Following The Daleks' Master Plan, episode 7, Strong, used his electronics knowledge to wire the audio output from the television into the Tape recorder. A highly dangerous procedure that breaks every rule of electrical safety but one that resulted in recordings that were crystal clear.

Strong was one of a small number of early fans who recorded audio from the now missing stories. However, he is believed to be the only one to record directly from the Television, resulting in the superior quality of his recordings.

In 1994 an accidental meeting with a Doctor Who fan who had contacts in the BBC brought his collection to the attention of the corporation. By this time the master tapes of most early episodes had been junked and the episodes were either missing or only existed as film prints. After reassurance that his tapes would be carefully cared for, Strong handed over recordings containing over 100 Doctor Who episodes.

Strong's recordings have been used for the animated releases of missing episodes such as Power of the Daleks. His recordings are so clear that they often exceed the quality available on the surviving film prints of the episodes, and as a result, a number of DVD's of early episodes contain audio taken from Strong's recordings rather than the film print.
