In the name of J.G. Ballard what does the J stand for?

James Graham Ballard (15 November 1930 – 19 April 2009) was an English novelist, short story writer, and essayist who first became associated with the New Wave of science fiction for his post-apocalyptic novels such as The Wind from Nowhere (1961) and The Drowned World (1962).

While much of Ballard's fiction would prove thematically and stylistically provocative, he became best known for his relatively conventional war novel, Empire of the Sun (1984), a semi-autobiographical account of a young British boy's experiences in Shanghai during Japanese occupation.

Described by The Guardian as "the best British novel about the Second World War", the story was adapted into a 1987 film by Steven Spielberg starring Christian Bale. In the following decades until his death in 2009, Ballard's work shifted toward the form of the traditional crime novel. Several of his earlier works have been adapted into films, including David Cronenberg's controversial 1996 adaptation of Crash and Ben Wheatley's 2015 adaptation of High-Rise.
