24450 Victorchang           Discovered 2000 Aug. 29 by J. Broughton at Reedy Creek Observatory.
As a youth Victor Chang (1936-1991) emigrated from China to Sydney, where he later trained as a heart surgeon. There in the 1980s he set up the first transplant center in Australia. His skill and technical improvements achieved the world's highest rate of patient survival.
