Enrico Clementi

from Wikipedia, the free encyclopedia

Enrico Clementi (born November 19, 1931 in Cembra ) is an Italian theoretical chemist ( quantum chemistry ).

Clementi studied chemistry at the University of Pavia , where he received his doctorate in 1954 , and was a post-doctoral student with Giulio Natta , M. Kasha, Kenneth Sanborn Pitzer and Robert Mulliken . Clementi was a researcher at IBM from 1961 to 1991 . There he was responsible for scientific computing in atomic physics and quantum chemistry and until 1974 manager of the scientific computing department at IBM's Almaden Research Center in San José. This also included research on parallel computers, biophysics and hydrodynamics. From 1974 to 1979 he was head of computational chemistry at the Istituto Donegani von Montedison in Novara and from 1979 to 1991 he was at the IBM research centers in Poughkeepsie and Kingston (New York).

From 1992 to 2000 he was a professor at the University of Strasbourg (Louis Pasteur University, METECC laboratory). From 1991 to 1994 he was also part of the Chimica Computazionale research group in Cagliari .

In 1984 he was a research professor at the Rensselaer Polytechnic Institute . In 1981 he was President of the International Society of Quantum Biology.

In the early 1960s, Clementi implemented Hartree-Fock programs for quantum chemistry at IBM, which he disseminated for free use (also in tables). He made the first systematic estimates of the correlation energy of atoms and molecules and in 1963 he also implemented density functional methods for atomic physics and quantum chemistry at an early stage and, from the early 1970s, codes for molecular dynamics and Monte Carlo methods (also freely available).

In the 1980s he was involved in parallel computer architecture (LCAP 1, LCAP 2, LCAP-3090, where LCAP stands for Loosely coupled array of processors ) and implemented parallel software for quantum chemistry and molecular dynamics.

He is a member of the International Academy of Quantum Molecular Science and received the Schrödinger Medal (1987). In 1970 he became an IBM Fellow , in 1987 he received the Dirac Medal from WATOC and in 2001 he received the Humboldt Research Award . In 1984 he became a Fellow of the American Physical Society . In 1999 he received an honorary doctorate in Namur.
