Answer
M, the enigmatic character from the James Bond franchise, is partly inspired by Mansfield Smith-Cumming, the first Chief of the Secret Intelligence Service (SIS). Smith-Cumming's unconventional approach to espionage, including his use of deception and double agents, influenced the creation of M's character. The character's portrayal as a shrewd and enigmatic leader reflects Smith-Cumming's own reputation as a master spymaster.
