Who have PhDs/doctorates that are also grandmasters?
Conditions:
standard GM only eg no WGM (see there for WGM version), no International Correspondence Chess Grandmaster
no honourary PhDs/doctorates
maybe kind of a cheat but I'll allow JD/MD (and LLB to the extent that LLB=JD) i.e. doesn't have to be Doctor of Juridical Science/Doctor of Medical Sciences. Also the other stuff here eg doctor of education or doctor of engineering, just no honourary.
Regarding Emanuel Lasker, I guess I'll allow like either world champion even if not a GM. As for the kinds of world champions allowed...ah fine just all of them: world standard, world rapid, world blitz, world fischer random (wesley so doesn't have a PhD. NEXT), world team chess, World Championship of Chess Composition, World Chess Solving Championship, and women's version of the preceding.
Re CW vs new answer: I personally don't care. But sites have rules/guidelines/discouragements so whatever. See the ff 2 comments re this
@BCLC A separate answer for each doctor/grandmaster? How many answers will that be, a hundred? Is that how these sites are supposed to work? I think they should all be in one ("community wiki") answer, and I suggested adding it to yours because it's the most extensive list that's been posted. – bof
and
@bof ok fine now it's community wiki but i don't care personally you can post answers but if it's better for the site then fine edit cw post or post your own answer or whatever – BCLC
Adding here in case comment gets deleted AGAIN (also seriously a downvote on the question after all the time I spent adding from the article of SecretAgentMan? WOW):
