This week saw the passing of Knut, the polar bear, at the Berlin zoo. He was only 4 years old. From the moment he was abandoned at birth by his mother and hand-reared by zoo keepers, he achieved great notoriety. In his short life he starred in his own film and made the covers of German Vanity Fair as well as the American Vanity Fair where he posed with Leo di Caprio. His antics were a great source of joy to the public and he will be greatly missed.
