In which radio programme did the morbidly super-intelligent character, Marvin, first feature?

Question

Which little girl in a pink-and-white striped dress did author and illustrator Joyce Lankester Brisley feature in her series of children's books?

Answer 1

The Hitchhiker's Guide to the Galaxy
Originally a 1978 radio comedy broadcast on BBC Radio 4, "The Hitchhikers Guide to the Galaxy" was later adapted to other formats, including stage shows, novels, graphic books, a 1981 TV series, a 1984 video game, and a 2005 feature film. Marvin was the story's paranoid android. Neither "Red Dwarf" nor "X Minus One" featured a super intelligent character called Marvin (or were broadcast first on radio).
