My friend Keith Neal, who has died aged 84, taught biology at Manchester grammar school (MGS) for 23 years, turning it from an elite, esoteric A-level to one of the most popular subjects at GCSE.
As head of department, and ardent environmentalist, he enthused his students through his knowledge and adventurous field trips. He was an internationalist, taking students to India in 1988 and 1993, and on a groundbreaking trip to China in the late 1990s.
