In the 1990s, Assistant Collections Manager Tom Gnoske and Adjunct Curator Julian Kerbis began researching the back story of the lions of Tsavo and in 1996 discovered the cave that Col. Patterson had christened the "Man-eaters' Den." MacArthur Curator Bruce Patterson (no relation to the Col.) began ecological studies of Tsavo lions in 1999 and headed the Earthwatch Institute's Lions of Tsavo project until 2009. All three Museum researchers continue their studies of lions amidst other responsibilities.
