I didn't watch the Oscars last night but I pulled up the In Memorium montage on YouTube and it looks like a few Trek veterans passed away last year:
Peter Berger, ACE, editor of Star Treks IV, V, Generations and Insurrection. It's a shame he was never interviewed for any of the DVD extras since I'm sure he had some stories to tell. (I'm only mentioning it here since I don't believe any of the other Trek websites mentioned it. According to IMDb, he passed away 9/22 at age 67.)
Gene Cantamessa, sound mixer on Star Trek IV (Oscar nominated) and VI...
...and Don Peterman, ASC, cinematographer on Star Trek IV (also Oscar nominated).
