It is with deep sadness that Zoo Berlin announces the passing of Fatou, our beloved western lowland gorilla and the world’s oldest known gorilla. On 1 September 2026, following a progressive chronic illness that could no longer be alleviated, Fatou was humanely euthanized in the presence of her long-time keepers and veterinary team. She was 69 years old.
Fatou had lived at Zoo Berlin since 1959 and was not only the zoo’s oldest resident but a truly remarkable personality. For more than six decades she captivated visitors with her calm and dignified presence. Zoo and Tierpark Director Dr. Andreas Knieriem said: “Fatou was a fascinating and calming presence who inspired countless people over the years and served as an important ambassador for the protection of western lowland gorillas. We are profoundly grateful for the long life she shared with us.”
In her advanced age, Fatou required specialized care. She lived in her own quiet enclosure, separate from the more active gorilla group, so that she could enjoy the peace she deserved. Her health was closely monitored by a team of veterinarians, curators and keepers. Curator Dr. Jennifer Hahn explained: “At this stage of life it is essential to pay close attention to individual needs and adapt care accordingly. Despite every effort — adjusted diet, pain management, enrichment and daily observation — the chronic illness advanced to a point where her quality of life could no longer be maintained. The decision to euthanize was made solely in Fatou’s best interest.”
Fruit had already been removed from her diet due to its high sugar content. She received several small, carefully selected meals each day, often distributed throughout the enclosure or placed in enrichment devices. When weather permitted, she continued to use her outdoor area and enjoyed quiet moments in the fresh air. These measures supported her for as long as possible.
Fatou arrived in Berlin in 1959 and witnessed many changes in both the city and the zoo. She leaves behind the current gorilla group: silverback Sango (21) and females Djambala (24), Bibi (29), Mpenzi (40) and Tilla (5).
Western lowland gorillas remain critically threatened by habitat loss and poaching. Animals such as Fatou remind us of our responsibility to protect endangered species and their natural habitats. Plans for a new gorilla habitat on the Zoo Berlin extension grounds continue. Support for this project can still be given via the Zoo Foundation: https://www.zoo-stiftung-berlin.de/unterstuetzen/zoo-berlin/tillas-villa.
We thank all visitors, supporters and staff who shared Fatou’s extraordinary life with us. She will be remembered with respect and gratitude.
