Ford Prefect (character)
Ford Prefect (also called Ix) is a fictional character in The Hitchhiker's Guide to the Galaxy by the British author Douglas Adams. He is the only character other than the protagonist, Arthur Dent, to appear throughout the entire Hitchhiker's saga. His role as Arthur's friend – and rescuer, when the Earth is unexpectedly demolished to make way for a hyperspace bypass at the start of the story – is often expository, as Ford is an experienced galactic hitch-hiker and explains that he is actually an alien journalist, a field researcher for the titular Guide itself, and not an out-of-work actor from Guildford as he had hitherto claimed.
Name
Although Ford had taken great care to blend into Earth society, he had "skimped a bit on his preparatory research," and thought that the name "Ford Prefect" would be "nicely inconspicuous." The Ford Prefect was a popular British car manufactured from 1938 to 1961, and Adams later clarified in an interview that Ford "had simply mistaken the dominant life form" of Earth. This was expanded on somewhat in the film version, where Ford is almost run over while attempting to greet a blue Ford Prefect. He is saved by Arthur and, in the film version of events, this is how the pair meet. The graphics in the TV series provide a similar explanation by listing a sequence of names including 'Ford', beginning with director John Ford, Arthur Ford, news reader Anna Ford, carmaker Henry Ford, the Ford Anglia, the Ford Consul with the final name Ford Prefect being selected.
