Remember Knut, the polar bear who had been rejected by his mother after being born at the Berlin Zoo and was later raised by a zoo keeper who strummed Elvis songs to him? Well, Knut was found dead in a pool of water today. The bear had become a worldwide phenomenon (bigger than Bieber) in 2006, after Thomas Doerflein, one of the zoo’s keepers, became his surrogate mother. Following Doerflein’s sudden death in 2008 from a heart attack, Knut was placed in an enclosure with several female polar bears in the hope he would find a mate. Sadly this was not to be. RIP Knut.
