Oscar Niemeyer is rumoured to be the designer of this year's summer pavilion at London's Serpentine Gallery in Hyde Park.
Born in Rio de Janeiro in 1907, and much influenced by Le Corbusier in his early career, Niemeyer is primarily known as the designer of the main public buildings of Brasilia (1957-79).
The pavilion would be his first project in the UK. It is not clear whether the architect would visit the completed scheme. Now aged 95, he is known to be scared of flying and did not make it to London when he was awarded the Royal Gold Medal in 1998.
The Serpentine established its policy of inviting a high-profile international architect to design a temporary structure for summer gatherings when it commissioned Zaha Hadid to design a venue for its 30th anniversary celebrations in 2000. Hadid was followed by Daniel Libeskind with his 2001 pavilion and Toyo Ito in 2002. Arup worked as joint designer with all three architects and will carry out the same role on this year's pavilion.
