It is now 30 years to the day since the mysterious death of Dian Fossey, the primatologist who transformed the way we see gorillas.
On 26 December 1985, Dian Fossey was hacked to death with a machete.
The 1988 film Gorillas in the Mist presented a fictionalised version of Fossey's story - worth watching over the holidays if you've not seen it.
