William Hartnell

Note that for the early Hartnell years, each episode of a serial had an individual title; no serial had an overall onscreen title until "The Savages". The earlier stories did have overall titles though they were not used onscreen and a lot of confusion has existed over the years, with many sources using different titles due to early fandom and reference works being unable to initially access the production files.
