There may be a reason that more detailed Feynman references haven’t been found: copyright. His papers are difficult to access (by appointment only to those “conducting research for which it is necessary”), not digitized, and you’re not allowed to reproduce them without permission from the Caltech (‘California Institute of Technology’) archives and his heirs. Thus, everything in their archives is apparently still on paper & undigitized, in this year of our lord 2023, despite being one of the most important & popular Nobelist physicists of all time whose apparently quite comprehensive papers* are stored in the archives of one of the wealthiest & most high-tech institutes in the world. As usual, copyright is why we can’t have nice things.
So, it’s entirely possible that ‘Young’ would pop up almost immediately if you went to LA and started browsing.
(I found this out while idly rechecking the citations about Feynman’s IQ being ‘only 125’ or whatever. I noticed that Gleick did provide a citation for that in the endnotes, and simply hadn’t included any body indication of that—I hate that style of citation for precisely this reason—and I noticed it by accident. He cites a speech to his old high shcool, which the Caltech archive has both transcript & audio—but you aren’t allowed access to it. Which is probably why only two authors appear to have ever cited the speech, despite it sounding like a major source on Feynman’s childhood; presumably they are the only ones to have made the pilgrimage. So, given the difficulty of accessing Feynman’s papers, the complete absence of any publicly-known information about Young tells us little about what the papers might contain.)
* Source is Feynman himself, regularly updating the corpus, so thickly covering the post-war period and presumably especially before 1974:
The Richard Phillips Feynman Papers were given to Caltech by Richard Feynman and Gweneth Feynman in two main installments.
The first group of papers, now boxes 1-20 of the collection, was donated by Richard Feynman himself beginning in 1968, with additions later. It contains materials dating from about 1933 to 1970. The second group occupies boxes 21-90. It was given to Caltech by Feynman’s widow Gweneth early in 1989. Group 2 contains papers primarily from the 1970s and 1980s, although some older material is present. Supplements since 1994 occupy three boxes and have come from various donors outside the Feynman family.
