US artist Richard Serra died on Tuesday in upstate New York at the age of 85. According to consistent media reports, he died as a result of pneumonia.
Most of Serra's works, many of them based on models made in Germany, are large and weigh several tons. He has created sculptures for more than 100 public places, from Philadelphia and St. Louis to São Paulo to Bochum and Kassel. However, he withdrew his design for the Holocaust memorial in Berlin amidst a dispute.
