Christopher H Bidmead is a Britishwriter and journalist.

He was Script Editor on Doctor Who from 1980-1981 overseeing the departure of the Fourth Doctor and the arrival of the Fifth. He has written 3 scripts for the series, Logopolis, Castrovalva and Frontios.

Bidmead trained as an actor at the Royal Academy of Dramatic Arts (RADA), later playing several roles on stage, television and radio. By the early 1970s he was scriptwriting for Thames Television, producing material for Harriet's Back in Town and Rooms. Up until 1979, he was a journalist.

In 1979, Robert Banks Stewart recommended him for the post of script editor on Doctor Who. Bidmead was primarily responsible for a 'back to basics' approach for his year long tenure on Doctor Who, attempting to curb the more playful and fantasy orientated approach of his predecessor Douglas Adams in favour of a more naturalistic and scientific style of presentation. Most noticeable in the more serious portrayal of Tom Baker's Doctor, this approach proved controversial and ratings suffered, although this has been attributed to the tough timeslot for Bidmead's season which saw it competing against Buck Rogers in the 25th Century on ITV. Very much a product of its time, Bidmead's writings for Doctor Whodemonstrate an increasing awareness of computer technology, typified by his complex serial Logopoliswhich served to write out the Fourth Doctor. After a year as script editor he returned to freelance work. This included writing two more Doctor Who serials for Peter Davison's Doctor (Castrovalva and Frontios) as well as producing novelisations of all three of these Doctor Who stories.

He has continued his career in computer journalism, writing regularly (as Chris Bidmead) for Personal Computer World, PC Plus and other computer magazines, and specialising in Linux tools. Occasionally he has contributed more speculative or philosophical pieces for publications such as New Scientist, and recently he has worked as a journalist producing material for Wired magazine.

In August 2006, it was announced in Doctor Who Magazine that Bidmead would be writing a Doctor Who audio play, Renaissance of the Daleks, for release through Big Finish Productions in March 2007. Chris Bidmead subsequently withdrew from this project in January 2007, although he did receive a 'From a Story By' credit for the play. In recent years, he has contributed voiceover commentaries and interviews for numerous DVD releases of his Doctor Who serials.

Tony Holland was an English television screenwriter best known as a writer and co-creator of the BBC soap opera EastEnders.

Holland began his career as an actor, appearing in the 1966 Doctor Who serial The Savages 

Other roles included  Message for Posterity, a serial for The Wednesday Play in 1967. That same year, a play he developed, The Isle is Full of Noises, was taken up by the BBC and produced by Thirty-Minute Theatre.

He landed a job on Z-Cars as a writer and script editor in 1970. It was here that he met producer and director, Julia Smith and started a long and successful working relationship.

In 1983 the BBC approached Holland and Smith to produce a new soap opera for BBC One to rival the long established ITV favorites. Thus, EastEnders was born.

Tim Barlow was a British actor who has performed many small roles in a variety of films,television programmes and plays.

Barlow left the army in 1969 to pursue a career in acting, receiving advice from Trevor Nunn and Sir Laurence Olivier. He has recently written and performed a one man show in which he describes how he came to the decision to go into the acting profession. He had previously had much success with another one man show entitled "My Army" in which he describes his life in the British army in the 1960s. This toured for many years.

One of his most notable roles was playing Mr. Morrow, a blind man allergic to his guide dog in The Tall Guy alongside Jeff Goldblum. He played Tyssan in the Doctor Who serial Destiny of the Daleks. He has also appeared on stage with the Royal Shakespeare Company and as the BFG at The Polka Dot Theatre in Wimbledon, and on screen as Mr Treacher in Hot Fuzz. Also in 2007 he played an Ancient Blind Oracle in the HBO series Rome.

He lost his hearing in the 1950s when testing a high Muzzle velocity Rifle for the British Army, until recently, when surgery to fit a cochlear implant allowed him to recover some of his hearing. His experience of having the cochlear implant fitted was detailed in a BBC Radio 4 programme called "Earfull - From Silence into Sound".

Donald Baverstock (18 January 1924 – 17 March 1995) was a British television producer and executive, born in Cardiff, Wales. He initially worked for BBC Television in their Talks Department, where he was the Editor of the topical magazine programme Highlight and then co-devised and edited its more ambitious and better-remembered successor Tonight, which began in 1957.

Baverstock worked on Tonight until 1961, when he was promoted to be the BBC’s Assistant Controller of Programmes across the whole television service. He did not occupy this post for very long, however, as in early 1963 he succeeded his superior Stuart Hood to become the Controller of Programmes for BBC One, in anticipation of the launch of the station's companion BBC Two the following year. In the same year he requested Sydney Newman to develop a new Saturday evening show for BBC One which would become Doctor Who.

However, soon after the launch of BBC Two in 1964, Controller Michael Peacock quickly began to run into difficulties, and BBC Director-General Hugh Greene decided in 1965 that the two men would be better suited to running each other’s channels, and took the decision to swap them over.

However, Baverstock felt insulted that he was being asked to take what he saw as a demotion to the lesser channel, and refused to take up his new post, instead resigning from the BBC altogether. He subsequently became involved in the establishment of the ITV northern franchise holder Yorkshire Television, becoming the company's first Director of Programmes and overseeing the creation of popular hits such as the soap opera Emmerdale Farm (from 1972).Despite being ensconced in Yorkshire, Baverstock did attempt to returning to Wales and applied for the vacant post of Controller BBC Wales. Former colleague Leonard Miall claimed in Baverstock's obituary in the Independent newspaper that the BBC Governors who interviewed him were "put off" by his "casual behaviour". Another factor may have been that, although born in Wales, Baverstock, like most of his fellow-countrymen, did not speak Welsh - an attribute considered essential for anyone aspiring to become Controller, Wales.^[1]

In 1957 Baverstock married Gillian Darrell Waters, elder daughter of British children's author Enid Blyton, at St James's Church, Piccadilly.

Biography from the Wikipedia article, licensed under CC-BY-SA

HARRY Stamper was an Edinburgh-born actor whose unique skill was his uncanny mastery of regional dialects, his repertoire extending far beyond his native Scotland.

Stamper, whose most successful work was performed in the 1970s, was master of almost the entire range of British dialects, be they Manchester north or Manchester south, Liverpool posh or Liverpool Irish, all delivered with a golden voice that accurately coloured every vowel and consonant.

It was a lifetime obsession. He would dismantle every dialect and intellectualise its structure and might, for example, offer friends informed discourses on the many minute variations of the word "hut" in various parts of Britain.

With Stamper, mimicry wasn't so much an art as a science, and it was a science he had mastered as few others in recent Scottish theatre

On one occasion he performed 56 separate voices in a single radio play, They Came to Britain, an achievement that earned him a place in the Guinness Book of Records.

During his most productive era he played usually small television roles in such classics as Dr Who, The Avengers, Z cars, The Saint, Softly Softly and The Wednesday Play.

He also performed in an even greater number of radio plays, which many saw as his forte, for although he was good looking his greatest talent lay in his voice, and radio was his best medium.

Perhaps his most notable stage appearance was at the 1977 Edinburgh Festival fringe, when he did a portrayal of Hugh MacDiarmid so accurate that even the usually thrawn MacDiarmid grudgingly admitted he had felt he was watching a younger version of himself. The play won Stamper a Fringe first, a greatly increased fan base and a lasting closeness to MacDiarmid.

He also wrote screenplays and produced a series of CDs of his own short stories.

Stamper's background was financially poor though culturally rich.

His father, a Geordie soldier, left his wife, Mary, and their four sons when Harry was still a baby and for the first 12 years of his life the family were to live in a single end in Hutchison, with Mary working as a nanny in Morningside and other wealthier parts of the city.

In the evenings Mary would sometimes settle her lively brood by doing hilarious impersonations of her employers and diverse others she had encountered during her day, and the young Harry was entranced and soon mimicking the mimic.

At night Mary would sleep on a couch in the front room while her four sons shared two beds, though they would all be up early doing paper rounds and any casual jobs available to make ends meet. Stamper's many tasks included working as a butcher's boy and several paper rounds.

Soon Stamper was apprenticed to a furniture maker, Martin's, in George Street, but he wasn't content and his passion lay with his hobby as a performer in amateur dramatic groups around town, for he had inherited his mother's skill as an impersonator.

Finally he got his break. A more senior member of one of his drama clubs had been asked to audition for Radio Scotland and had asked Stamper to "chum" him along and sit in the waiting room to give him courage. An assistant producer mistook the waiting Stamper for a youngster who had been called for another audition and he seized his chance, pretended he was the other candidate and landed the part.

His subsequent career was largely one of intensely focused effort on various small roles, the drudgery made tolerable by intermittent glory. He travelled the world in search of theatre work, particularly to Canada, and when he wasn't acting would fill in doing causal jobs or lecturing in drama.

Such a lifestyle wasn't easy for one so hugely talented and passionate about his calling and he sometimes sought solace through drink.

On such occasions a darker side would sometimes emerge, though many attributed this to his understandable frustration.

His private life was less fraught. He enjoyed supportive and stable relationships within his family and in 1968 became happily married to Helen Redmond, daughter of the renowned film actor Liam, though they divorced amicably around ten years later.

In middle age he was to partner Betty Huntly Wright in a successful relationship which ended only at her death in 1991, a loss from which he never fully recovered.

Stamper's latter days were not his best. He would become profoundly depressed and several of his latter stage performance were more expansive than the plays' authors might have wished.
