Dear Bernie, If by trees in CS you mean at least in part the abstract data type, Knuth gives a short history and bibliography on pp. 406-7 of the first volume of The Art of Computer Programming, the section beginning with "Trees have of course been in existence since the third day of creation..." On p. 459, he gives a little more on the history of trees as CS data structures in particular. Happy to send photos of these pages if they'd be of use! I think the files are too big to not get bounced by the list though. Sincerely, Jeff ________________________________ From: Members <members-bounces@lists.sigcis.org> on behalf of Bernard Geoghegan <bernardgeoghegan2010@u.northwestern.edu> Sent: Thursday, March 26, 2020 4:05 PM To: Sigcis <members@sigcis.org> Subject: [SIGCIS-Members] Tree diagrams in computer science and other fields (i.e. genealogy) Dear Colleagues, A little query sent across the lockdowns and quarantines: Can anyone recommend scholarship on the tree-style diagrams that circulate both in computer science and a wide range of other fields, for example, genealogy, kinship? Is there any good work on the history of these diagrams, their intersection, and what they might say about possible links in styles of reasoning across fields that might, otherwise, seem remote?
