Sir David

I like animals. I like natural history. The travel bit is not the important bit. The travel bit is what you have to do in order to go and look at animals.
David Attenborough

The Regent Theatre was full. And full of all sorts of people: young and old, dread-locked and conservative, and all of them were waiting for the legendary film-maker, naturalist and story-teller to enter the stage. When he did, we could have been at a rock concert. The crowd went wild. But when he began to speak, you could have heard a pin drop, such was the collective awe and reverence this man inspires.

86 years old. 60 years working with animals and plants and sharing it with the world. And he continues to share his love of the natural world. When asked what he would have been if he hadn't been an intrepid presenter, he replied that he didn't really know but that he might have been a teacher. He would have been the best kind of teacher, but instead of touching a cohort of children he has enlightened generations of children and adults all around the world.
