I missed this information, well covered by Kay Olson at The Gimp Parade.
Harriet McBryde Johnson was/is one of my heroes for writing so well, so accurately about the disability experience -- particularly of her youth. If you are of an age (I, too, am 50) and experienced a segregated childhood, I urge you to read Accidents of Nature. My review of that book is here: http://teriadams.blogspot.com/2006/06/novel-that-tells-it-like-it-was-and-is.html
The Gimp Parade: RIP Harriet McBryde Johnson, 1957-2008
