Francesco Calogero (born February 6, 1935) is an Italian physicist, active in the community of scientists concerned with nuclear disarmament.


He is the son of the philosopher Guido Calogero. After his father was sentenced to national exile by fascist police, Francesco Calogero spent more than one year (1942) in Scanno, a small Italian village. After World War II, Calogero graduated "laurea in fisica" cum laude at University of Rome La Sapienza, on February 1958. He became Professor of Theoretical Physics, in the same university in 1976.

Physics research[edit]

Calogero's scientific publications in English include four books and about 400 papers (about half with co-authors). His main research concerns integrable many-body problems. Several solvable many-body models and nonlinear evolution partial differential equations (PDEs) are named after Calogero in the mathematical physics literature. He also formulated the Calogero conjecture that quantum behavior is caused by the stochastic component of the local gravitational field due to the chaotic component of the motion of all particles of the Universe due to their mutual gravitational interaction.[1]

Peace activism[edit]

Calogero served as Secretary-General of Pugwash Conferences on Science and World Affairs from 1989 to 1997, and from 1997 to 2002 as chair of the Pugwash Council, of which he still is an "ex-officio" member. He published (in Italian and English---some with co-authors) nearly 400 papers and several books on world affairs.

He was a member of the Governing Board of the Stockholm International Peace Research Institute from 1982 to 1992.[2]

He accepted on behalf of Pugwash the 1995 Nobel Peace Prize, jointly awarded to Pugwash and to Joseph Rotblat (Oslo, 10 December 1995).[3]
