Charles Quinn (To the Last Man)

Dr Charles Quinn fell victim to an alien parasite at the age of thirteen and was placed in quarantine by Torchwood One. His life was saved by the work of the pioneering surgeon, Dr Jan Van Nellen, but it was necessary to keep him under observation for some years.

His education was provided by Institute staff including Van Nellen. Quinn soon became his protégé. On taking his doctorate, he was recruited by Torchwood Three. During his time there he made several significant studies of alien anatomy. He later moved into a teaching role at Torchwood, but was killed in an air raid on Cardiff during World War II.
