Henrietta Goodheart

Henrietta Goodheart, known more familiarly as Netty, was an astronomer at Greenwich Observatory until 2006. By 2009, she was suffering from Alzheimer's disease but remained lively and gregarious. Wilfred Mott was very close to her, perhaps romantically, and shared a confidence with her about what his granddaughter had told him of her travels with the Tenth Doctor. She was briefly possessed by the Mandragora Helix. At some point during World War Two she was married for three days before her husband was caught in the bombs in Singapore. She sang "when stars begin to fall" as her husband died with his hand in hers.(PROSE: Beautiful Chaos)

She was also a member of the Silver Cloak. On Christmas Eve, 2009, Wilf called her for help locating the Tenth Doctor; she then called June, whose sister had seen the TARDIS. (TV: The End of Time)
