Elisa Frota Pessoa, born Elisa Esther Habbema de Maia (17 January 1921 – 28 December 2018), was a Brazilian experimental physicist. She was one of the first women to graduate in physics in Brazil, in 1942, and a founding member of the

deuterons
with nuclei of average masses.

Early life

She was born in Rio de Janeiro, daughter of Juvenal Moreira Maia and Elisa Habbema de Maia. She began to become interested in science in 1935, in the ginasial (middle school) at the Escola Paulo de Frontin. Her greatest influence was professor Plinio Süssekind da Rocha with whom she took physics classes. He followed her closely and guided her, giving her subjects outside the program to study. At the end of high school Elisa wanted to study engineering, against the will of the family, since her father, who was very conservative, considered that the best career for women was marriage. This, however, did not prevent her from enrolling in the Physics course of the Faculty of Philosophy of the University of Brazil (current Federal University of Rio de Janeiro), graduating in 1942.[1][2]

Career

Together with Sonja Ashauer,[3] who graduated the same year at USP, she was the second woman to graduate in physics in Brazil. Soon she excelled in the course and in the second year, was called by professor Joaquim da Costa Ribeiro to be his assistant. She worked with Costa Ribeiro, without receiving a salary, until 1944, when she was hired by the university. At the age of 18, she was married to her former teacher, the biologist Oswaldo Frota-Pessoa, with whom she had two children, Sonia and Roberto. In 1951, she separated of the husband, and started to live with the also physicist Jayme Tiomno.

Along with Tiomno and other graduated physicists at the same time, such as

Mario Schenberg, she promoted science in Brazil, at the same time facing prejudice being a woman and separated from her husband in a time when divorce was illegal in Brazil. In 1949, she was one of the founders of the Brazilian Center for Physical Research (CBPF), where she was Chief of the Nuclear Emulsions Division until 1964.[4]

In 1950, she published with

K mesons.[6][7]

Frota Pessoa moved to Brasília in 1965, to work in the

AI-5 in April 1969. Fleeing from the military dictatorship persecution, she worked in Europe and the US, where she collaborated in the training of Brazilian physicists. In 1975, Elisa began setting up an emulsion laboratory at PUC with the assistance of Ernst Hamburger from IFUSP. Two years later, in 1977, as a member of the Experimental Physics Department at IFUSP, she continued her work at PUC in collaboration with IFUSP. In 1980, she resumed her work at CBPF, implanting a nuclear emulsion laboratory for nuclear spectroscopy.[8][9][10]
Even after compulsory retirement, in 1991, she remained until 1995, as an emeritus professor at the center.

Death

Elisa died on 28 December 2018, in Rio de Janeiro.[11] She left five grandchildren (a biochemist, an art historian, an economist, an engineering student and a high school graduate) and six other great-grandchildren.
