From Rick Sternbach on FB:
Some of us had heard inklings earlier but the news is now out. Greg Jein has passed, and the film and miniature world is a better place for his having lived in it and contributed so much. I first got to meet Greg in the late 70s, and followed his exploits up to and beyond the times he and his colleagues brought some of my Star Trek ship designs to life. Thank you for your friendship, and your amazing talent.
