A few years ago, at Goodwill, I found a lovely 1930s copy of Eve Curie's biography of her mother Marie Curie. The book had been well-preserved in a homemade mylar jacket. In the flyleaf were two inscriptions: one a woman's name with "Dr", dated in the 1970s; the other dated in the early 2000s with another woman's name, also a doctor. When I flipped through the pages, a "Congrats grad" card fell out. Dr. A was Dr B's mother and had given her this book from her own library upon Dr B's graduation from med school.
