Emma, Lady Hamilton (born Amy Lyon; 26 April 1765 – 15 January 1815), was an English model, dancer and actress. She began her career in London's demi-monde, becoming the mistress of a series of wealthy men, culminating in the naval hero Lord Nelson, and was the favourite model and muse of the portraitist George Romney.
In 1791, at the age of 26, she married Sir William Hamilton, British ambassador to the Kingdom of Naples, where she was a success at court, befriending the queen who was a sister of Marie Antoinette, and meeting Nelson.
