who won the frist oscar for a film ? do u know that?

This was easy I just looked it up on the internet. Of course there was no way for me to know and I have never even heard of this person or this film. But it was Mercedes McCambridge (a woman) for her role in the 1949 "All The King's Men" film. You can read about her here. http://www.signonsandiego.com/uniontrib/20040317/news_1m17mccam.html
