This weekend sees a slew of programmes to commemorate the 90th birthday of naturalist and broadcaster Sir David Attenborough, who has been enchanting viewers with his peerless wildlife documentaries for over 60 years.
And of course, during that time the iconic TV figure has racked up an impressive number of Radio Times cover shoots – 22 at the current count – so we thought we'd collect them together to showcase the impressive range of one of Britain's most recognisable faces.
Take a look at Sir David's life in TV programming below.
