I would say that Tonia Harding is the most famous USA figure skater currently in the world. That quite praised movie about her 'skating life' certainly helped in that regard. I can bet that around Europe Katarina Witt, Pluschenko, and Torvill/Dean are still the most famous skaters in their disciplines. The fact is that all those skaters were part of the sport during 3 or 4 olympic cycles. Torvil/Dean Bolero performance was the most recognizable olympic performance of all athletes performances in Sarajevo 1984, and that 'fame' i'm afraid we will never see again from figure skating at Olympics.
