By CHRISTINA LARSON and TAMMY WEBBERIn her 91 years, Jane Goodall transformed science and humanity’s understanding of our closest living relatives on the planet — chimpanzees and other great apes. The tributes also included pledges to honor Goodall’s memory by redoubling efforts to safeguard a planet that sorely needs it.

Grandson Merlin and granddaughter Angelo work with the institute, while grandson Nick is a photographer and filmmaker, Lewis said. There also are Jane Goodall Institutes in 26 countries, and communities are leading conservation projects in several countries, including an effort in Senegal to save critically endangered Western chimpanzees.
