Actually a lot of peeps did!
DJ Premier inspired me in the sense of showing me that sampling could be something really creative and innovative, and more than just looping.
RJD2 inspired me in the same way DJ Shadow apparently inspired elphonics.
The Alchemist inspired me in the way he makes his chops. Sometimes really advanced - sometimes so simple.
9th Wonder inspired me A LOT (as you can hear if you listen to my beats), first and foremost cuz I love soul-music, and secondly because he made it "graspable" (is that a word? I'm not English, so...
). 9th showed me that sampling is something I can do on my own with a cheap app (FL Studio) and be good at, cuz, although I love his production-style, it's often easier to analyze how 9th has chopped and manipulated his samples (compared to, for example, DJ Premier).
Also some newer producers I'm inspired by are M-Phazes, Khrysis, Sicknature (Danish producer), Snowgoons (German producer-team), Adam Kay (young Danish producer who REALLY has skills... sounds like a mixture of Pete Rock and Premier), and of course Boon Doc (who inspired me to buy an MPC, although I keep using FL on the side)...
That's it I guess...
EDIT: I forgot Just Blaze, who inspired me for the same reason as kyng
EDIT 2: I also forgot Pete Rock!!
