Margaret Whigham, Duchess of Argyll attending an event in 1934. Margaret had been the most famous and feted debutante of her age. Husband the 11th Duke of Argyll claimed she had committed 88 adulteries. Sex photo emerged after he broke into her house and stole diaries. Never before had a duchess been exposed on camera performing what was then coyly referred to as a ‘sex act’ and rarely, if ever, had such a photograph been produced in a divorce case.
