Angela Meder: Undi carefully examines little Moseka, the first gorilla who was reared by its mother at Stuttgart Zoo. Undi herself treated her babies very roughly at that time and they were therefore reared by humans. (© Angela Meder 1984)

Angela Meder: The pictures where taken during my study of gorilla infant development when I spent thousands of hours watching gorillas. I witnessed very emotional moments there and sometimes I could take photos as this scene between Moseka and Undi. (© Angela Meder 1984)
