DR JEANNE - your uncle was the camera operator on Mr Selznick's SINCE YOU WENT AWAY.
THANKS, JACK! So the photo's in your book, huh? The IMDB says SINCE YOU WENT AWAY was produced in 1944, which makes sense, because Eddie was still slim and dashing in that photo. All my memories of him are of a heavy-set man.
My cousin Marion SHOULD be the family historian, as she grew up in Old Hollywood, but I'm afraid she lost much of her memory long ago. And I came along too late and missed much of the action!!
