I studied History with George at Cambridge.
Aside from a brilliant analytical mind, George is excellent at presenting complex subjects in an easy and engaging way.
He could explain the long term causes of the English Civil War as if he was telling you the plot of his favourite blockbuster over a coffee. And you'd come away feeling as thrilled by it all as he clearly was.
His boundless energy and good humour is infectious, and makes him a great presenter and communicator.
