|Never one to shirk her duty, during World War II Hannah volunteered for the Hanover Fire Department, becoming the first woman volunteer ever. As the smallest and the lightest, she was often the first one up the ladder to fight the fire. When she moved to Norwich, Vermont in 1963, she retired from the force. The department later honored her with a life membership with voting rights. Ironically, though tragically, her volunteer hours did not help her fight a fire that destroyed her own house in 1989. Aside from volunteering at the fire department, Hannah kept busy outside of her research, tending an organic garden, doing carpentry, writing poetry, using her mechanical skills to make her own equipment, and being a friend to many. In later life, a friend gave Hannah a puppy, Maggie, that inspired her to write a children's book about his adventures. Whatever she wanted to do, if Hannah set her mind to it, she would do. Nothing could stop her, neither gender nor age.|
Towards the end of her life, Hannah began spending her winters in Santa Rosa Florida, and her summers in Norwich. In 1994, she moved to Florida
full time. In 1999, at the age of 93, Hannah died at her home in Florida.
