The actress Katherine Hepburn has died. Her career spanned more than half a century, and encompassed a breathtaking diversity of work. She won her first Oscar in 1933 for Morning Glory, and her last, for On Golden Pond, 48 years later. Her work with Spencer Tracy is the stuff of cinema legend, and she was completely at home in roles from Cleopatra to Violet Vennable. Hepburn was 96.
