I recall clipping an article, maybe as far back as ten years ago, titled something to the effect of "Whatever Happened to Helen Keller?" - meaning, her fame and legacy in today's world.  It looked like something I'd find fascinating, but I don't think I ever got around to reading it (got lots of stuff like that, unfortunately).  I can almost promise that I will find it somewhere in this house, so if/when I do, and if it turns out to be any good, I'll post.
