Reinhard “Leo” Kuenkel was born in Berlin and raised in Wetzlar. After graduating from high school in Weilburg, he travelled to the area of Tanzania that borders Lake Victoria, where his passion for wildlife became a force that completely changed his life. His photography books Serengeti, the original edition of Ngorongoro, and African Elephants have been published in five languages, and his first documentary on African elephants for German television has been aired on BBC and National Geographic Channel.
Craig Packer was born in Texas and received his undergraduate degree from Stanford University in 1972. While still at Stanford, Packer went to Tanzania to study baboons with Jane Goodall at the Gombe Stream Research Centre. He then went to the University of Sussex to complete his Ph.D. research on the Gombe baboons. After a study of Japanese macaques in Hakusan National Park, Packer returned to Tanzania in 1978 to head the Serengeti lion project. He subsequently held a post-doctoral position at the University of Chicago and joined the faculty of the University of Minnesota in 1983, returning to the Serengeti for several months each year. Packer received a J.S. Guggenheim Fellowship in 1990, became a Distinguished McKnight University Professor in 1997, and was elected to the American Academy of Arts and Sciences in 2003. He is the author of “Into Africa,” which won the 1995 John Burroughs medal, and more than 100 scientific articles, most of which are about lions. His research has been supported primarily by grants from the National Science Foundation.
