A towering dandy who exemplified a certain kind of Victorian English eccentricity very much in vogue in 1960s London, there was a time when Procktor could do no wrong. In the spring of 1964, the gallerist Bryan Robertson invited him to take part in an exhibition of young painters at the Whitechapel Gallery. The New Generation exhibition defined the progressive artistic mood of the day, and included work by Bridget Riley, Patrick Caulfield and Hockney. Lord Snowdon and his then wife Princess Margaret attended the private view and, to coincide with the launch, a selection of sculptures was displayed in the grounds of Kensington Palace and a glamorous party was held. Procktor and the Princess would become great friends, and she spent many evenings in the candlelit rooms in Manchester Street. 'He was very friendly with her, even when she was a worse boozer than him. There were certain qualities in those people, and perhaps in Princess Margaret, being a sort of failure, and a drunk and all the rest, that appealed to him,' recalls his friend James Kirkman.
