1971. The author of Born Free here offers her opinion on the book Innocent Killers by Jane Goodall and Hugo Van Lawick to the book's publisher, opining that "it would have been better to concentrate on one species at a time, instead of undertaking too many animals in different places, and with too many people involved. I also think it is a mistake to have to keep up family obligations when one is doing research on animals." Written on Elsa Wild Animal Appeal airmail stationery. Signed by Adamson. Her books about raising an orphaned lion cub, and following up with its offspring in later years were bestsellers in the 1960s and made into an academy Award-winning film. They helped change the perception of the relationship between humans and "wild" animals, and the need for conservation -- as Jane Goodall's books did over her lifetime and beyond.
