- The mark of a great mathematician is someone who not only cracks a big open problem that has defeated previous generations of mathematicians, but who then goes on to create tools for future generations. And Lennart Carleson can really be described in those terms, says Marcus du Sautoy.

Marcus du Sautoy's presentation of Lennart Carleson's work is available on the Abel Prize website.

After the presentation Marcus du Sautoy did a telephone interview with Carleson who only hours before the announcement had been told that he was the winner of the 2006 Abel Prize by the Academy's Secretary General.
