Literary heroes Arthur C. Clarke and Ladybird founder Douglas Keen have been added to the ultimate obituary collection: the Oxford Dictionary of National Biography
2001: A Space Odyssey author Arthur C. Clarke and Douglas Keen, the creator and publisher of Ladybird books, of which Bunnikin's Picnic Party (pictured) was its first success in 1940, join jazz musician and radio broadcaster Humphrey Lyttelton, TV personality Jeremy Beadle and playwright Harold Pinter to the comprehensive list of biographies.
The Dictionary is now updated to 2008, chronicling those who died in that year and the colourful lives they led. Other noteworthy people added to the posthumous collection are Frederick Hart, the inventor of the Ford Cortina, Bagpuss creator Oliver Postgate and The English Patient director Anthony Minghella.
Almost 60,000 life stories are included in the newly updated dictionary, which is written by more than 13,000 authors, the newest contributors including Melvyn Bragg, Michael Billington and Douglas Hurd.
No living person is included in the dictionary, which is updated three times a year.
