Named in honor of Arthur N. Cox, one of the graduate student observers in the early years of the Indiana minor planet program and the first recipient of a Ph.D. in the graduate program established after the gift of the Goethe Link Observatory {see planet  (1728)} to Indiana University in 1948. His four years at Indiana University included a six-month expedition, initiated by John B. Irwin {see planet  (3959)}, to the South African observatories to introduce photometry by photoelectric methods to the southern hemisphere. Cox then moved to Los Alamos National Laboratory, becoming the leader of a scientific research group studying both nuclear test results and stellar astrophysics. His calculations of stellar opacities in the early 1960s enabled considerable progress to be made by many stellar astrophysicists, and they are used even now some 30 years later. (M 19335) _ _.
