I recently found this YouTube interview from Computerphile with John Hughes, the inventor of Haskell. He explains what functional programming is and where Haskell came from, and how exactly they came up with the name.
Thanks for the video clip, liked it. As you had mentioned, John Hughes is an inventor of Haskell (I think you meant one of the inventor designers), and its been said that Haskell programming language is a product of a committee. Some of the prominent ones of the designers are: Simon Peyton Jones, Paul Raymond Hudak, Philip Lee Wadler, Lennart Augustsson, John Launchbury and Erik Meijer.
