David Attenborough, 96
David Attenborough’s voice is almost as famous as his conservation work. This legend of nature documentaries continues to present into his 90s, and it would be hard to imagine a documentary about nature without the iconic British man’s voice explaining the action. Even at 96 years old, he regularly travels across the world to visit many of the locations in person that his documentaries are based on–which thoroughly demonstrates his commitment to the cause.
Attenborough was knighted by Queen Elizabeth II in 1985 for his significant contributions to television and natural history.
