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

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

Tributes are expected to be offered by a member of the Goodall family with other speakers to be announced.

There were a group of 20 therapy dogs from a group named PAL, or People Animals Love, that greeted her urn and funeral guests.
