Rock-and-roll trailblazer Bo Diddley died this morning of heart failure at his home in Archer, Florida. He was 79. His health had been failing in recent years; he'd suffered a stroke last May and a heart attack three months later. Known as "the Originator," he was the credited inventor of the "Bo Diddley beat," once unironically fronted a band called the Hipsters, and leaves behind a legacy of classic hits including "Who Do You Love?" and "Bo Diddley."
