Thomas Heatherwick is a designer architect from London and the man behind the Olympic Cauldron.
The cauldron was lit on 27 July at the end of the end of the Olympics opening ceremony, which was directed by Danny Boyle.
The design of the cauldron had been one of the most closely-guarded secrets of the opening ceremony. When the competing delegations arrived in London, they each received a copper petal, inscribed with the name of their country and the words ‘XXX Olympiad London 2012’. They carried these petals into the stadium during the opening ceremony before laying them down on the cauldron. When all the petals had been laid down, the seven torchbearers each ignited a single tiny flame within one of the copper petals on the ground, triggering the ignition of all 204 petals. The Cauldron’s long, stainless-steel stems then rose towards each other and converged to form one single flame.
