Prince François of Orléans, Count of Clermont (François Henri Louis Marie; 7 February 1961 – 30 December 2017) was the eldest son and heir apparent of the Orléanist pretender to the French throne, Prince Henri, Count of Paris, Duke of France and Duchess Marie-Thérèse of Württemberg. François was thus the Dauphin of France in Orléanist reckoning. However, his mother had been infected with toxoplasmosis during her second and third pregnancies, and the pre-natal exposure left both Prince François and his younger sister, Princess Blanche, developmentally disabled.
