John Hartman

Hartman served in the British military. (AUDIO: Through the Ruins) His daughter Yvonne disliked him, wishing that she could say the same about her own father as Rachel Allan did hers. (AUDIO: New Girl) The family moved around a lot because of his career. (AUDIO: Through the Ruins)

In the 1970s, Anne told her husband that Yvonne would not be attending boarding school. Rather, she would attend the local comprehensive so as to mix with people from varying backgrounds. (AUDIO: The Rockery)

After a hiker was found dead in the woods by Fetch Priory, Dr Fendelman instructed Maximillian Stael to "get on to London. Tell Hartman I want a security team here within two hours." (TV: Image of the Fendahl) Security files on the Fendahl reached the Torchwood Institute through Yvonne, who had obtained them from her father. This was a deliberate plan by the Fendahl to have the files cross Gwen Cooper's path. (AUDIO: Night of the Fendahl)

Hartman enjoyed gardening. (AUDIO: The Rockery)
