Theory:Timeline - First Doctor

This page lists appearances of the First Doctor in the order in which he experienced them. This timeline is based upon observations of the Doctor Who universe and the events that occur during each of these stories. From these observations we have attempted to build a concise timeline. It is assumed, much like its TV story counterparts that for each novel, comic story and audio series their published/numbered order is the order they occur in. This does not apply to short stories which are often ambiguous about their placement. There are also many gaps between stories.

The layout of this timeline is in part based on the observations on Doctor Who Reference Guide and Doctor Who - The Complete Adventures, as well as information in Lance Parkin's AHistory which allow us to make observations on placement of stories, such as Doctor Who Reviews, Doc Oho's Book Reviews, The History of Doctor Who, The Discontinuity Guide, Clive Banks Databank, Whopix, the Big Finish forums, The Whoniverse and the Divergent Universe forums. None of these sources should be used solely as a source or considered a "true" timeline for stories.

Additionally there are statements on the back of Virgin Missing Adventures and BBC Past Doctor Adventures novels that state between which TV stories the novel takes place between. These can be used to narrow the field, and should be viewed as the only placing for these novels.

TV Comics placement
The First Doctor's travels with John and Gillian are very problematic to place in the Doctor's timeline, as between The Experimenters and The Extortioner, the Doctor is inexplicitly replaced by his second incarnation.

The stories Conundrum and The Land of Happy Endings hypothesise that these adventures are either stories created by The Master of the Land of Fiction or the Doctor's dreams.
