According to Alan Gribben's _Mark Twain's Library: A Reconstruction_,
Mark Twain's essay "The Walt Whitman Controversy" classes Wilde's
poetry with the "new bad books" of Whitman and Swinburne; he owns
none of these works (see file DV36, Mark Twain Papers).
In her book _My Father Mark Twain_ Clara Clemens writes about the
family crossing paths with Wilde in Bad Nauheim (p. 113) in a
dining room. To her knowledge, that was the first time Clemens and
Wilde had met.
