85158 Phyllistrapp           Discovered 1987 Oct. 17 by C. S. Shoemaker at Palomar.
Phyllis Trapp (b. 1952) has been an inspiration to many with her indomitable spirit during her courageous 18-year battle with breast cancer. Devoted to her family, she volunteered in her grandsons' school, encouraging and teaching students through her love and patience, and playing the piano for kindergarten performances.
