13376 Dunphy           Discovered 1998 Nov. 15 by I. P. Griffin at Cocoa.
Desmond Plunket Dunphy (1920-1998) was an Irish medical doctor. In a career lasting from 1945 to 1980 he patiently and diligently tended many tens of thousands of patients, both in Ireland and later in family practice in England. During the last decade of his life he provided much inspiration and encouragement to the discoverer.
