Christopher H. Bidmead

Christopher Hamilton Bidmead wrote three Doctor Who TV serials, all of which he also novelised. He was also script editor for season 18.

He was attached (agreed, but without a contract) to write several serials that were ultimatelly cancelled. They were In the Hollows of Time, a two-part (forty-five minute) story for the cancelled season 23, and a four parter, Pinacotheca (a.k.a. The Last Adventure), which would have been the third part of the The Trial of a Time Lord arc.

He also contributed to the charity reference book Behind the Sofa: Celebrity Memories of Doctor Who.

Contributions to the mythos
Major characters and concepts created for or debuting in a Christopher H. Bidmead script include:
 * Fifth Doctor
 * Tegan Jovanka
 * The TARDIS' Cloister Room, Cloister Bell and Zero Room.
 * The concept of a regeneration going wrong to the point of possibly failing (a plot development repeated with later incarnations).
 * The concept of an "in-between" Doctor, in this case the Watcher (later, arguably, the Valeyard fit into this category, too).
