Louis, 4th duc de Noailles

Louis, 4th duc de Noailles (21 April 1713 – 22 August1793), who bore the title of duc d'Ayen until his father's death in 1766, when he became duc de Noailles, served in most of the wars of the eighteenth century without particular distinction, but was nevertheless made a marshal of France in 1775. He refused to emigrate during the Revolution, but escaped the guillotine by dying in August 1793, before the Terror reached its height.

He was succeeded by his son, Jean-Paul-François.
