Watching this show, American Oz, about L. Frank Baum..... https://www.pbs.org/wgbh/americanexp...s/american-oz/

think Baum could have been EIE and his wife LSI.... a bit surprised by that I guess, suppose I haven’t thought about it that much before and I haven’t seen anything on this forum about them or the Oz books...

if anyone has any thoughts about it, figured I’d throw it out there
