German artist Otto Piene has died aged 86, a day after his latest exhibition opened in Berlin.
The painter and sculptor passed away on Thursday (17Jul14) and reports suggest he died in a taxi in Berlin, Germany while on his way to the city's Neue Nationalgalerie gallery, where a display of his work opened the previous day (16Jul14).
Piene is most famous for his Olympic Rainbow - an art piece which was displayed above Munich at the close of the 1972 Olympic Games in the city which was marred by a terrorist attack on the Israeli team.
He is also known for founding the Zero group of experimental artists with Heinz MACk in 1957.
Piene's works were exhibited all over the world and he was honoured with the Leonardo da Vinci World Award of Arts award in 2003, and in 2006 he accepted the Sculpture Prize from the American Academy of Arts and Letters.
