John was an achiever and an irrepressible ideas man. He was able and imaginative and everything he did was tackled with seemingly boundless energy and total conviction. His huge enthusiasm was catching and a very striking feature of his life was the way in which those who knew him, and especially those who worked with him, were inspired and motivated by his personality. He was charismatic and slightly eccentric and possessed a keen sense of humour and a very infectious laugh. He was one of the most distinguished foresters of his generation and achieved great things and won many friends and admirers.
