Thanks, Robert - I never would have known. He was a delightful man, and welcomed me - and various film crews - on many occasions into that magical, time-warped house overlooking Kenisngton Gardens, where Barrie had written "Peter Pan". His mother Kathleen had been married to Captain R F Scott (of the Antarctic) who wrote that wonderful last letter to Barrie as he lay dying in his frozen tent, so in many ways was a last link to JMB. The Times obituary seems particularly apt:
Urbane in manner, witty in speech, and everyone’s conception of a truly civilised person, he possessed to a high degree the gift of making and keeping friends. He lived throughout his life in a large house in Bayswater Road, where J. M. Barrie — a friend of his mother — had written Peter Pan. The house was a much-loved home for Young’s large family and the venue of many enjoyable parties, and he rejected repeated offers for the site from developers.
I do so hope that his wife Elizabeth - a very remarkable woman and anthropologist - can keep all such developers at bay for many years to come.
