Funeral services for conservationist Dr. Jane Goodall were held Wednesday at Washington National Cathedral.

Goodall became a household name for her groundbreaking chimpanzee field research.

Among the tributes was one given by actor Leonardo DiCaprio.

"Most people knew her as Jane Goodall, the icon, the legend, but the Jane I was fortunate enough to get to know was gentle, curious, funny, witty, and absolutely unstoppable," he said. "She could light up a room with her stories and somehow inspire everyone she met to believe that they individually could do better. We got to cross paths in so many different places. At conferences, on panels, and in friends' homes. And every single time, we'd end up tucked away in a corner, talking late into the night about politics, biodiversity, and our shared hope that the next generation might do better than we have done."
