It looks like Leslie (Mike) Pace, Recruitment Manager for BOAC. He was my Step-Father, who later married my late Mother, Catherine Pace (formerly Kitching, Maiden name Long) in about 1958. She, too, had worked for BOAC: in Comet Accounts. I believe he had interviewed her, as head of recruitment, or at least knew of her through the recruitment process. They were happily married for more than 25 years.
He had a fascinating history: starting in Aviation as an Engineer with either A.T & T. or Instone Airways, later working with Imperial Airways. I remember him attending Sopwith Apprentices Dinners, although he was never an Apprentice: being with Sopwiths as an ‘Improver’. He was awarded an MBE for his part in moving staff, etc., from Bristol to the new Heathrow. He knew everyone and could well have been longer in aviation than anyone else in BOAC at that time. Because of his very low Staff Number he was able to travel anywhere, with guaranteed seats, anywhere in the World. My Mother’s first ever trip abroad was with him to Barbados.
