  Pierre Deligne
Pierre Deligne (born 3 October 1944) is a Belgian mathematician.
From 1970 until 1984, when he moved to the Institute for Advanced Study in Princeton, Deligne was a permanent member of the IHÉS staff.
During this time he did much important work, besides the proof of the Weil conjectures: in particular with George Lusztig on the use of étale cohomology to construct representations of algebraic groups, and with Rapoport on the moduli spaces from the 'fine' arithmetic point of view, with application to modular forms.

 Deligne biography
Although Deligne was an undergraduate at the Free University of Brussels from 1962 to 1966, he spent the academic year 1965-66 at the École Normale Supérieure in Paris.
Deligne remained based at the Institut des Hautes Études Scientifiques until 1984 when he went to the Institute for Advanced Study at Princeton in the United States, where he was appointed a professor.
A remarkable feature of Pierre Deligne's thinking is that, when confronted with a new problem or a new theory, he understands and, so to speak, makes his own its basic principles at a tremendous speed, and is immediately able to discuss the problem or use the theory as a completely familiar object.

 Deligne-Mumford moduli space of curves   (Site not responding. Last check: 2007-10-31)
In mathematics, the Deligne-Mumford moduli space of curves is a refined construction of a moduli space of algebraic curves, that is work from 1969 by Pierre Deligne and David Mumford.
It combined two novel techniques in algebraic geometry, Mumford's geometric invariant theory and Michael Artin's algebraic stacks, to construct a moduli object (not a scheme), including enough stable curves, and for which the irreducibility of the space of curves could be proved.

A solution of the three Weil conjectures was given by Deligne.
The areas on which he has worked, in addition to algebraic geometry, are Hilbert's 21st problem, Hodge theory, theory of moduli, modular forms, Galois representations, L-series and the Langlands conjectures, and representations of algebraic groups.
In addition to the Fields Medal, Deligne was awarded the Crafoord Prize of the Royal Swedish Academy of Sciences in 1988:-

 Not Even Wrong » Blog Archive » Deligne Conference
Deligne has spent most of his career at the IHES and at the Institute, and this conference was in honor of his 61st birthday (I suspect they initially planned it for last year, but it got pushed back).
Deligne worked with Grothendieck at the IHES during the late sixties, and is perhaps best known for his proof of the Weil conjectures completed in 1974, an achievement which won him a Fields medal in 1978.
The Weil conjectures motivated much of the work by Grothendieck and others in algebraic geometry during the fifties and sixties, and Deligne was able to finish a proof using Grothendieck’s machinery as well as some different ideas of his own.

For major contributions to several important domains of mathematics (like algebraic geometry, algebraic and analytic number theory, group theory, topology, Grothendieck theory of motives), enriching them with new and powerful tools and with magnificent results such as his spectacular proof of the Riemann hypothesis over finite fields (Weil conjectures).
Pierre Deligne became famous in the mathematical world at an early age through his brilliant proof of the “Weil conjectures”, which concern the number of solutions of systems of polynomial congruences (the so-called “Riemann conjecture over finite fields” is part of them).
Because of the conciseness of his style and of his habit of never writing the same thing twice (in fact, quite a few of his best ideas have never been written!), the volume of his publications is a true measure of the richness of his scientific production.

Deligne's conjecture on 1-motives, L. Barbieri-Viale, A. Rosenschon, M. Saito
We reformulate a conjecture of Deligne on 1-motives by using the integral weight filtration of Gillet and Soulé on cohomology, and prove it.
If the degree of cohomology is at most two, we can prove the conjecture for the Hodge realization without isogeny, and even for 1-motives with torsion.

Il primo traguardo di Pierre Deligne è stato seguito da molti altri di uguale importanza.
Una notevole caratteristica del pensiero di Pierre Deligne si riassume nel fatto che, ogni qualvolta egli si confronta con un nuovo problema o una nuova teoria, egli capisce e, per così dire, fa suoi i concetti basilari con una velocità sorprendente.
Pierre Deligne, da solo o in collaborazione con altri, ha scritto circa un centinaio di lavori, la maggior parte dei quali di notevole lunghezza.

 Classical Motivic Polylogarithm according to Beilinson and Deligne, by A. Huber and J. Wildeshaus
Based on the unpublished preprint [BD] of Beilinson and Deligne, we give the construction of the classical polylogarithm in the motivic cohomology of a certain simplicial scheme and compute its regulators in absolute Hodge and etale cohomology.
As a consequence, we obtain an alternative proof of Beilinson's theorem on the regulator of the cyclotomic elements in the K-theory of an abelian number field.
Another consequence is the validity of Conjecture 6.2 of [BK], and hence, of the Tamagawa number conjecture for Tate twists up to powers of two, also for twists of odd parity.
