Antoine de Guiscard
Antoine de Guiscard (1658 – 17 March 1711), also known as the Marquis de Guiscard or the Abbé de la Bourlie, was a French refugee who attempted to assassinate Robert Harley, a British statesman, on 8 March 1711 by stabbing him with a penknife during a Privy Council meeting at Whitehall.
Harley, though stabbed and bruised, recovered. Guiscard was fatally wounded and died just over a week a later in Newgate Prison.
