Dian Fossey was an American gorilla zoologist who studied gorilla groups for 18 years in Rwanda. She did a lot of conservation work in Rwanda, including opposing poaching and tourism, as well as attempting to preserve gorilla habitats. She was murdered in 1985.
According to Adam One, Dian "embodied an ideal we [the God's Gardeners] hold dear: loving care for all Creatures." She is one of their more important saints, and her saint day is dedicated to celebrate "interspecies empathy."
She also had a hymn dedicated to her.
