Fossey then met Joan and Alan Root, native wildlife photographers who were working on a documentary of African gorillas at the time, and when the couple brought her along on one of their trips in search of the primates, Fossey was instantly enamored. She later explained her draw to gorillas in her 1983 autobiographical work, Gorillas in the Mist: "It was their individuality combined with the shyness of their behavior that remained the most captivating impression of this first encounter with the greatest of the great apes," Fossey said. "I left Kabara with reluctance, but with never a doubt that I would, somehow, return to learn more about the gorillas of the misted mountains."
