Sonny Rollins, Wayne Shorter, Benny Golson, Herbie Hancock (a little younger), Chick Corea (noted Scientologist), just to name a few off the top of my head. All of them are still playing fairly regularly, too.

Ron Carter, who played with Shorter and Hancock in Miles' second Quintet, is still active. Mid '60s, though.

Don't forget Roy Haynes

Plus Cecil Taylor, McCoy Tyner, and Ahmad Jamal! (Can't believe I left them off the first time.)
