Isabelle Christian Holland (Jun 16, 1920 — Feb 9, 2002) was born in Basel, Switzerland, where her father was the American consul. She spent her early years in Guatemala City and Liverpool, England, and moved to America in 1940 after war broke out. She earned a bachelor's degree from Tulane University in 1942 and settled in New York, where she held various publishing jobs. One of the first books she worked on as a publicity director at J. B. Lippincott Company was "To Kill a Mockingbird" by Harper Lee, with whom she began a lifelong friendship. Ms. Holland wrote more than 50 books but was not published until her late 40's. Known for her young-adult novels tackling serious subjects, she also wrote gothic suspense and mystery thrillers. Her 1972 novel The Man Without a Face was the basis for the 1993 Mel Gibson film. She was still at work at the time of her death at 81. — [from the New York Times]
