She was also the first person to win the Best Supporting Actress Oscar (for ANTHONY ADVERSE).
Oops! I guess somebody beat me to that one. Sorry about that.
However, she was also blacklisted for years because her husband was one of the "Hollywood Ten".
She was a very nice and interesting lady. I had the priviledge of interviewing her years ago when I was writing a column for the now long gone CORONET Magazine.
