Douglas Trumbull
By 
The film special effects master Douglas Trumbull has died at the age of 79.
I just did the math and this means he was about 25 when he and Stanley Kubrick hammered out 2001: A Space Odyssey.
That film and Blade Runner, another one of his signature works, are two creations that have become part of the permanent furniture of my mind, as well as those of countless other people.
RIP.
