12113 Hollows           Discovered 1998 July 29 by J. Broughton at Reedy Creek Observatory.
New Zealand-born Fred Hollows (1929-1993) was an ophthalmologist who saved the sight of thousands of aboriginal and poor people in third-world countries rather than make a comfortable living at home. His work outlives him, following his training of local doctors and establishing local interocular lens factories.
