One thing which suddenly strikes me amazing (though it should not) is that Welles was rare, even among "boy geniuses." A fair number of them are written up each year, but like "The Quiz Kids" of the 1940's, they seldom do much extraordinary in their adult lives. Welles did.
I also liked Roger Hill's reference to Welles' trip to Central Europe. We see the influence of that experience in his life and work, but unlike his journey through Ireland, we don't have much of a record. Nor of the journey to China, for that matter. Curious that such a precocious lad, such an apparently gregarious one, would not have made friends here and there, would not have had correspondence, indeed love letters. Do the scholars among us find much of that?
