Deutsch speculated it was "either Bill or Dick Lyon" (sic) (https://web.archive.org/web/20040203202935/http://www.aladdi...) but there has been speculation he meant Tom Lyon, who worked there at the time. Gosling had them hosted on his website for a long time (https://web.archive.org/web/20021206065457/http://java.sun.c...)

Yes, he didn’t really know. So the original attribution is fuzzy

Gosling still has them on his present day site https://nighthacks.com/jag/blog/401/index.html
