Source-derived summary

Demetrios Christodoulou (Greek: Δημήτριος Χριστοδούλου; born 19 October 1951) is a Greek mathematician and physicist, who became well known for his proof, together with Sergiu Klainerman, of the nonlinear stability of the Minkowski spacetime of special relativity in the framework of general relativity. Christodoulou is a 1993 MacArthur Fellow.

Early life

Christodoulou was born in Athens and received his doctorate in physics from Princeton University in 1971 under the direction of John Archibald Wheeler. After a temporary position at Caltech, a full professor position at the physics department of the University of Athens shortly followed at the age of 21.

He visited CERN and the Max Planck Institute for Physics. His also was given an indefinite paid leave to Paris to study mathematics and to Courant. He became professor of mathematics, first at Syracuse University, then at the Courant Institute, and at Princeton University, before taking up his last position as professor of mathematics and physics at the ETH Zurich in Switzerland. He is emeritus professor since January 2017 and an honorary professor of the departments of mathematics and physics at the University of Crete and Brown. He holds dual Greek and U.S. citizenship.

Achievements

In 1993, he published a book coauthored with Klainerman in which their proof of the stability result is laid out in detail.

Editorial summary

The public source identifies “Demetrios Christodoulou” as greek-American mathematician. This brief keeps that definition visible, then builds a research path around Demetrios, Christodoulou and Greek-American.

Editorial reviewStrongest as a route into the people, institutions and dated events that shaped the subject’s public record. The current lead gives the account dated anchors—1951, 1993, 1971, 2017—that can be checked directly. The linked authority record independently contributes the date 1951-10-19. Its value is orientation rather than verdict, with Demetrios, Christodoulou and Greek-American providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Demetrios Christodoulou”, the useful work is to connect “greek-American mathematician” to the records capable of establishing context and consequence.

Evidence profile

The entry’s evidential value lies in the named roles, institutions and publications that can be tested against primary documentation. The source revision retrieved here is dated Sep 25, 2026. The linked authority identifier is Q687024. VIAF identifies the subject as 111441558. The Library of Congress control number is n86810248. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1951, 1993, 1971 and 2017.

Critical limits

Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Read biographical claims against dates, named institutions and the cited references. Distinguish a subject’s later reputation from evidence produced during their lifetime.
