Further to my previous message, a highly readable account of Clemens' meetings with the inventor Jan Szczepanik is ch. 10 ("The Austrian Edison") of Carl Dolmetsch's _Our Famous Guest: Mark Twain in Vienna_ (Athens and London: U of Georgia Press, 1992), pp. 198-213. As Dolmetsch explains, Szczepanik also invented an early form of television. In addition to a couple of photos of the weaving machine, this chapter has some great, hitherto unpublished portions of Twain's notebook. Taylor Roberts <[log in to unmask]>
