Jean-Dominique Cassini (1748–1845), a.k.a. Cassini IV, studied the behavior of chronometers at sea. He succeeded his father, Cassini de Thury {see planet (24103)}, as director of the Paris Observatory and with him published an account of the observatory’s first 100 years. He also completed his father’s map of France. (M 46684) _ _.
