Arthur C Clarke, 1917 - 2008 
"Any sufficiently advanced technology is indistinguishable from magic."
This quote has been one of my favorites for most of my adult life. In pretty much every job I've done the people I work for seem to see what I do as magic. To me such work never seemed to so advanced, or so challenging as to be mystical, but fun. And admittedly I often did enjoy the idea that I knew something that others didn't, that I was able to do things that others can't. In some respects that idea is also a curse as it is often seemingly true that nobody else can do what I do, which results in much stress. Still, that quote has been the mantra for my life.
To me, Arthur C Clarke was a magician. His abilities to write and understand not only current technology, but where it could realistically go and then create a brilliant story around it, was astounding.
He is now indistinguishable from magic.
