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. (PROSE: Beautiful Chaos)
