24103 Dethury           Discovered 1999 Nov. 9 by C. W. Juels at Fountain Hills.
César-François Cassini (1714-1784), a.k.a. Cassini de Thury or Cassini III, succeeded his father, Jacques Cassini, in 1740 as third director of the Paris Observatory. He was also a cartographer and was instrumental in producing the first modern map of France using the triangulation method.
