Nov. 12 (UPI) -- The life of Jane Goodall was honored Wednesday at Washington National Cathedral where hundreds, including actor Leonardo DiCaprio and Rep. Nancy Pelosi, paid their final respects to the famed British primatologist and conservationist.

Goodall, 91, died of natural causes on Oct. 1 in Los Angeles while on a speaking tour.

The service, hosted by the Jane Goodall Institute USA, began with a 20-dog salute on the cathedral steps in honor of her favorite animal, the canine.

"The world mourns your departure, and I ask you that please touch those around the world who are as heartbroken as we are," Goodall's grandson, Merlin van Lawick, said during the service.
