Henrietta Goodheart

Henrietta Goodheart, known more familiarly as Netty, was an astronomer at Greenwich Observatory until 2006. Before this she lived in Singapore around the same time as World War Two. She met a man named Richard Philip Goodheart and they married. Three days later during a bombing campaign, they were caught in the blast and Richard died holding her hand as she sang "When the stars begin to fall". She vowed never to marry again and that no other man came close to Richard except for Wilfred Mott. By 2009, she was suffering from Alzheimer's disease but remained lively and gregarious. She was able to make light of her condition even joking about the times she would wander the streets in her underwear. 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. (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)
