Ronnie James Dio(1942-2010)

Introduced the "horns" gesture (created by extending the index and pinky finger, with the middle and ring fingers held under the thumb) to the world of rock music. Audiences would start repeating the gesture and its popularity soon spread. To this day, it's still widely seen at virtually all hard rock concerts, and is used by audience members to reflect their enthusiasm for the music.

I was in [Black] Sabbath at the time. The gesture was a symbol that I thought was reflective of what that band was supposed to be all about. It's NOT the devil's sign like we're here with the devil. It's an Italian thing I got from my Grandmother. It's to ward off the Evil Eye or to give the Evil Eye, depending on which way you do it. It's just a symbol but it had magical incantations and attitudes to it and I felt it worked very well with Sabbath. So I became very noted for it and then everybody else started to pick up on it and away it went. But I would never say I take credit for being the first to do it.
