Alan Turing is named BBC's 20th Century Icon after passionate speech from Chris Packham

This is a short, but nevertheless impressive, passionate and measured presentation from Chris Packham. 

Scientist and World War Two codebreaker Alan Turing has been named 'The Greatest Person of the 20th Century' in the live final of BBC Two's Icons series. 

On Tuesday (February 5), Turing won the public vote after being up against fellow finalists Dr Martin Luther King, Nelson Mandela, Ernest Shackleton, David Bowie, Muhammad Ali and Pablo Picasso.

Let me know what you think about the presentation.
