Biography

Oort studied from 1952 to 1958 at Leiden University, where he graduated with a thesis on elliptic curves. He received his doctorate in 1961 in Leiden from Willem Titus van Est and Jaap Murre with thesis Reducible and Multiple Algebraic Curves,[1] but had previously studied under Jean-Pierre Serre in Paris and Aldo Andreotti in Pisa. Oort was from 1961 at the University of Amsterdam, where he became a professor in 1967. In 1977, until his retirement in 2000, he was a professor at Utrecht University.[2] He was a visiting scholar at several academic institutions, including Harvard University (1966/67) and Aarhus University (1972/73). In 2008 he was the Eilenberg Professor at Columbia University.

His research deals with, among other topics, abelian varieties and their modules. In 1994 he formulated what is now known as the André–Oort conjecture (generalizing a conjecture made in 1989 by Yves André).[3] In 2000 Oort proved a conjecture made by Grothendieck in 1970.[4] Oort was a co-author of an article on Poncelet's closure theorem[5] and the author of An aspect of harmony in music of Johann Sebastian Bach.

In 1962 Oort was an Invited Speaker with talk Multiple algebraic curves at the International Congress of Mathematicians in Stockholm. In 2011 he was elected a member of Academia Europaea.[2] In July 2013 he gave a talk at the International Congress of Chinese Mathematicians in Tapei.[6]

His doctoral students include Michiel Hazewinkel, Aise Johan de Jong, Hendrik Lenstra and Joseph Steenbrink.[1]

He was married to (and is now divorced from) author Marijke Harberts, who wrote Afschied van Joke Smit (1987 biography of Joke Smit), Doezamand: Roman (1994 novel based upon her life as a student), and Eerlijk gezegd: Interviews met vrouwen (1974 collection of interviews with women); the couple have three grown sons, among whom is the Ultimate Frisbee player Jeroen Oort.

gollark: No.
gollark: Historically technological advances have at least eventually replaced lost jobs (not that I think jobs created/lost is a good way to judge innovations) but I suppose you could argue that AI is different somehow. It definitely would be if AI stuff started being able to make more AI stuff, but you would probably run into bigger issues than high unemployment then.
gollark: It also seems unlikely that we would suddenly jump from the current situation where a bit of stuff is automated and quite a lot isn't to everyone being immediately unemployed, so you can notice and do stuff about it in the interval. Restructure the economy for post-material-scarcity or whatever. No idea how that would *work* but oh well.
gollark: If you can make robots/AI/whatever do any work you want easily, I'm sure you could make a few to produce food and whatever without problems.
gollark: Also, congratulations on successfully (so far) navigating the horrors of the UK university system.
