Squeak..

I've mentioned it before, and it's a book, not web accessible, but "Reading Jazz" by Robert Gottlieb is booked as "a gathering of autobiography, reportage and criticism". It contains information on most old school players, all the way back to Jelly Roll Morton, Willy "The Lion" Smith, Mary Lou Williams and many others. It's the best read on jazz and jazz piano players I've ever found.

Hope that helps.
