Arthur Wellesley, 1st Duke of Wellington
His response in 1824 to John Joseph Stockdale who threatened to publish anecdotes of Wellington and his mistress Harriette Wilson, as quoted in Wellington — The Years of the Sword (1969) by Elizabeth Longford. This has commonly been recounted as a response made to Wilson herself, in response to a threat to publish her memoirs and his letters. This account of events seems to have started with Confessions of Julia Johnstone In Contradiction to the Fables of Harriette Wilson (1825), where she makes such an accusation, and states that his reply had been "write and be damned".
