The images of Twain cavorting in Tesla's lab which Cheney includes in TESLA: MAN OUT OF TIME are certainly brimming with possibilities. I picked this book up from the library, not realizing that Cheney borrows pretty generously from John O'Neill's material in PRODIGAL GENIUS on the Twain/Tesla relationship. I've seen the Cheney work cited on this list a number of times, by several different people, I believe, and I am wondering why Cheney has received most of the recognition and attribution for this material. I thought maybe Cheney had new material which O'Neill might not, but, in comparing their works, I don't see much evidence that this is the case, at least in the Twain vignettes. Cheney's are a bit more imaginative and narrativized, but I don't necessarily consider this a strength because it converts what might be factual into a series of apocryphal stories. Any thoughts about these differences? Any ideas on why Cheney's work is cited instead of O'Neill's? (besides that hers is more recent) I'm quite interested in how people might be using these references. Meryem Ersoz University of Oregon
