My friend Janet Shapiro, who has died aged 84, was a mathematics lecturer and campaigner for the rights of pensioners. She devoted much of her spare time to working with the National Pensioners Convention, as well as with the Hornsey Pensioners Action Group in north London.
She was a fierce defender of the NHS as a member of Haringey Keep Our NHS Public and she also belonged to her local Labour party’s health and care group. In addition she was a prolific letter-writer and correspondent to her area’s newspaper, the Ham & High.
