Paulo Leal Ferreira (1925( 

1925-2005) 2005) 

INSTITUTO DE FÍSICA TEÓRICA 

Main responsible for the existence (since 1952 till now) of a 

Research Institute, the 

INSTITUTO DE FÍSICA TEÓRICA (IFT), 

internationally recognized for research activities in Physics. Located 

in Rua Pamplona, 145 – Bela Vista, São Paulo, IFT is today the main 

institution for research and graduate studies in Physics of UNESP - 

Universidade Estadual Paulista; and one of the main Physics 

research institution of our Country. 



2006




Before the creation of IFT, in 1946, Paulo Leal Ferreira was an assistent 

professor of Gleb Wataghin and David Bohm in the University of São Paulo 

(USP). From that time, it was registered a letter from Leite Lopes to 

Wataghin, with offer of an assistent position to Paulo Leal Ferreira in Rio de 

Janeiro. In the words of Leite Lopes (see Leite Lopes virtual library): 

“Passei os anos entre 1946 e 1949 tentando obter algum apoio, alguma 

bolsa para estudantes, uma vaga de assistente - quando tentei, em vão, 

nomear Paulo Leal Ferreira que, com o seu irmão Jorge, cursara Física em 

São Paulo - e dinheiro para aquisição de livros e revistas científicas.” 



2006




Near the year 1950, Paulo and Jorge were already engaged in the same 

ideal of their father, Eng. José Hugo Leal Ferreira, of a research 

institution in São Paulo. 

In all his life, since 1952, Paulo Leal Ferreira was completely 

dedicated to this ideal represented by IFT, a research institution in 

Physics. His personal history and scientific achievements can be 

traced by the history of IFT.

The existence of IFT till now became possible due to the dedication 

of Paulo Leal Ferreira, that with the help of his brother Jorge Leal 

Ferreira (1928-1995), followed the ideal of their father, Eng. José 

Hugo Leal Ferreira. 

The ideal of Eng. José Hugo Leal Ferreira was a research 

institution dedicated to fundamental science, in a time when research 

activities are very rare in Brazil. In his words (documented in 1971): 

``Os instituidores tiveram por principal escopo realizar duas tarefas 

básicas: assegurar, de início, a presença de cientistas autênticos e de 

alto nível, e organizar o IFT como fundação para desfrutar de plena 

liberdade de pesquisas e de administração, a coberto de influências 

perturbadoras de qualquer natureza e procedência.´´ 



2006




Among the friends that help him to realize this ideal, 

Eng. José Hugo Leal Ferreira never forget to pay a tribute to 

Lauro Monteiro da Cruz, member of the Federal parlament, representing 

São Paulo for several years, physician and physicist by USP, professor 

(Medical Physics) in the Escola Paulista de Medicina; and 

Henrique B. D. Teixeira Lott, a militar that, after returning from a mission 

in United States, got a clear consciousness of the necessity to support the 

fundamental science. He studied how the financial support was being done 

in USA, from institutions and people donations. 

When returning to Brazil, he promptly join the mouvement for the foundation 

of the IFT. As declared by Hugo Leal Ferreira in 1971, without Lott, IFT 

could not have being created and subsisted. 



2006




We should note that these people were not physicists, or even engaged in research activities. 

Eng. José Hugo Leal Ferreira, Lauro Monteiro da Cruz, Henrique B. D. 

Teixeira Lott, and others that follow the same ideal, like Samuel Ribeiro (that made a 

donation for the IFT original instalation), José Reis (a member of the Board of IFT for about 

20 years), and Francisco Luiz Ribeiro (lawyer) had just the patriotism and the clear 

perception of the necessity to develop fundamental research in a institution outside of the 

conventional university structure existent in Brasil at that time. 

The time was the same of the creation of the CBPF, the Brazilian Center for Physics Research, 

by J. Leite Lopes, J. Tiomno and others in Rio de Janeiro. CBPF was also created under the 

same perception, as a research institution, independent of any existent University structure.

Paulo and Jorge Leal Ferreira were already engaged in 1951 in the 

original organization of IFT, by contacting well-known physicists in Europe to 

conduct the scientific direction of the institution. 

In the following years, their main role was with the administration of the new 

institution, as well as organizing scientific activities with the visitor scientists. 

We should note that, Paulo Leal Ferreira try to administrate the institution 

in a way to give conditions to the visitors to produce research, as well as to 

the young group of Brazilians working in IFT to learn with them, such that in 

future could produce independent research.

Paulo Leal Ferreira was the First Brazilian 

Scientific Director of IFT, in 1961, after the 

period of Japanese direction. 

From 1961, the coordination of research 

was done by Brazilians directors, with the 

help of several short and long period 

visitors, invited to give lectures and 

graduate courses, or to specifically 

collaborate in some research of interest to 

members of the institution.

1971 – Establishment of the Graduate School at the IFT 

Financial support: BNDES (Banco Nacional de 

Desenvolvimento Econômico e Social), and 

FINEP (Financiadora de estudos e Projetos). 

FINEP was the main funding agency providing support to pay salaries, after 

the first years of the institution when the support was also possible to obtain 

from banks and private institutions. In the 1980’s, Finep stop providing support 

to pay salaries to scientists and staff of IFT. 

1986 – Agreement with UNESP to provide payment of salaries 

1987 – All the personal of the IFT are transferred to the Universidade Estadual 

Paulista (UNESP), creating the Instituto de Física Teórica of UNESP. The 

Fundação IFT, owner of the land and predial instalations, remains giving 

support to the scientific activities of this institution.

Instituto de Física Teórica and Brazilian Journal of Physics 

In the period of the Japanese scientific direction (Taketani and Miyasima) the research 

and collaborations were better stablished in IFT. 

It is from this period the introduction of a bulletim published in IFT from 1958 to 1967, 

named Boletim de Física Teórica e Experimental - Informações entre 

Físicos. This bulletim was inspired by Taketani, as informed by Paulo Leal 

Ferreira, the General Editor of the Bulletim. 

The bulletim, circulating among Brazilian scientists in a period when the communications 

between continents were very limited, became an important element to people working in 

our institutions, to obtain information on research being made in other countries (usually 

from Brazilians visiting other laboratories and institutions). 

This bulletim, edited by Paulo Leal Ferreira, was followed by the Brazilian 

Journal of Physics, which started with the name Revista Brasileira de Física. It was 

edited in IFT from 1971 to 1978 by Jorge Leal Ferreira (30/03/1928-26/02/1995). 

Jorge Leal Ferreira was the President of Fundação IFT from 1973 till 1985.

III A SBF na ditadura - 1969 

Em abril de 69 foram aposentados pelo regime militar o presidente da SBF, Jose Leite Lopes, no seu segundo 

mandato, o vice-presidente, Jaime Tiomno, e o conselheiro Mario Schenberg. Jaime Tiomno nem chega 

a tomar posse - numa carta comovida a diretoria apresenta a sua renúncia e faz um apelo para que a sociedade 

continue funcionando. Leite Lopes também renuncia e viaja para os Estados Unidos. ...O Boletim numero 1 da 

SBF, editado pelo secretário-geral Ernst W. Hamburger, surge em novembro de 69 sob o signo do 

protesto. O CNPq havia recusado um pedido de recursos da Diretoria anterior para publicar uma revista 

científica. Nessas condições, a solução foi conseguir o patrocínio de anunciantes para publicar um boletim com 

informações de interesse para os professores e pesquisadores de física brasileiros". A idéia consistia em 

suplementar os boletins do Centro Latino-Americano de Física, CLAF, que desapareceriam logo depois, e 

preencher o papel das antigas ‘‘Informações entre Físicos", publicadas pelo IFT em São Paulo. 

IV A SBF na ditadura – Primeira metade da década de setenta 

Durante os anos mais difíceis da ditadura, embora permanecendo no exterior, Leite Lopes foi mantido na 

presidência da sociedade... 

Em 71 a diretoria permanece praticamente inalterada, com Alceu Pinho na vice-presidência e Marcio Quintão 

Moreno, da UFMG, substituindo Ramayana Gazzinelli na secretaria de ensino. ... Realiza-se um dos primeiros 

levantamentos da pós-graduação em física no Brasil. Propõe-se a criação da Revista Brasileira de Física (RBF), 

escolhendo-se Jorge Leal Ferreira (IFT) como editor geral, Carlos A. Dias (UFBA), Alceu G. Pinho Filho 

(PUC-RJ), Jose Goldemberg (IFUSP), Ramayana Gazzinelli (UFMG), Sergio M. Rezende (UFPE), Marco A. 

Moreira (UFRGS) e Abraham H. Zimerman (IFT), como editores regionais. 

Jorge Leal Ferreira foi editor da RBF de 71 a 78, sendo sucedido por Henrique Fleming (1978-1983)

About his retirement 

He was retired compulsory, under the Federal legislation, CLT, due to 

an internal normative rule of UNESP. The University did not pay 

attention to the fact that the retirement at the age of 70 is not, in 

principle, compulsory under the CLT legislation. 

In case being allowed by Unesp to remain active for a few years after 

the age 70, he will be benefited by the transformation of the working 

regime law. 

Previously, all the working contracts of people in IFT was regulated by 

the federal CLT regime. In 1998, the contracts are transfered to the 

public São Paulo state regime, with the advantage of full salary 

retirement. 

As a result, his retirement pension was less that 20% of his previous 

salary (obviously not enough to pay his expensive medications).
