I was all set to to photograph the Prime Minister [Winston Churchill] from the best side and at the best angle, as he sat in an armchair in his library. But Churchill shook his head. ‘Young man,’ he called me ( I was fifty-two at the time). ‘I know how to take pictures. You have to do it from there.’ In order to please the great man I photographed him ‘from there’, and then discreedtly skipped back to the opposide side and got the picture I wanted.
