In another thread of mine about Elizabeth II’s honorary doctorates, senoy remarked upon the Queen’s embarrassment at her lack of formal education. This got me thinking, do any members of the British royal family have formal education over and above an undergraduate degree? That is, are there any with real doctorates or even a real Master’s degree? (By “real” I mean that the degree was conferred after formally enrolling in a program that required coursework, research, a thesis, and/or examinations. This discounts honorary doctorates and the Master’s degrees that Oxbridge hand out like free candy to former students.)
I browsed through the first dozen or so entries in Wikipedia’s line of succession to the British throne but so far it looks like everyone has at most a B.A. or B.Sc. (Charles has a free-candy M.A. from Cambridge, which doesn’t count for the purposes of this question.) How far down the list do I need to go before I find someone with a real Master’s degree? How about a doctorate? If there aren’t any on the list, then how about the royal families of other countries?
