For more than 70 years, British broadcaster and naturalist, Sir David Attenborough has brought nature to our screens.At 100, he reflects on one unforgettable moment - coming face to face with mountain gorillas in Rwanda.Here’s that encounter from 1979.

Twenty years ago, Congolese man Guy Goma came into the BBC for a job interview but, in a now legendary case of mistaken identity, ended up live on the BBC News Channel. Speaking to BBC Africa, Guy explained how he managed to stay calm under the unexpected pressure of live TV.

“When I’m darker, nobody sees me. It’s like I am invisible. I’ve always been complimented when I’m lighter.” Focus on Africa Podcast host Charles Gitonga spoke to South African software developer Masheane Sefuthi, who has been on a journey to ‘whiten’ his skin.

It's Sir David Attenborough's 100th birthday and in 1980 he faced questions from an audience of young viewers about his life and television career. Lesley Judd hosted the show, and Attenborough talked about making a connection with gorillas, and his concerns for the environment.
