My husband, Alan Hill, who has died aged 81, had a long career teaching mathematics and subsequently worked tirelessly to improve the local environment in Fletcher Moss Park, Didsbury, Manchester. He established a nature reserve there, led weekly walks and natural history groups, and acted as a leader of the garden volunteers.
The son of Connie (nee Payne) and Frank Hill, Alan was born in Madras, India, where his father was a textile chemist. In 1951, Alan’s parents sent him and his younger brother to boarding school in Buxton, before moving back to the UK themselves four years later.
