Susan George is a political scientist and writer on Third World poverty, underdevelopment and debt. I heard about her in the news of 07/07/2008 on Democracy Now - there were protests in Japan during the G8 summit and Susan George was among the protesters who were blocked from entering Japan, together with Lydinyda Nacpil, the Asia-Pacific coordinator for Jubilee South (more here).
More about Susan George e.g. on en.wikipedia or on the pages of Transnational Institute where she is a fellow. Also I found two youtube videos: 1, 2 and a related video on debt.
