Marília Chaves Peixoto

Following her work on convex functions, Peixoto was appointed an associate member of the Brazilian Academy of Science on 12 June 1951. She was the first Brazilian woman to join the organization, and the second woman after Marie Curie, a foreign associate of the academy.

Peixoto married Maurício Peixoto in 1946. The couple jointly published "Structural Stability in the plane with enlarged boundary conditions" in 1959, one of several papers which led to Peixoto's theorem.

Peixoto graduated from the Federal University of Rio de Janeiro in 1943 with a degree in engineering, having also studied mathematics at the university and acted as a monitor for the university's National Faculty of Philosophy. In 1948, she received a doctorate in mathematics, and began teaching at the Escola Politécnica da UFRJ. In 1949, Peixoto published "On the inequalities y ″ ≥ G ( x , y , y ′ , y ″ ) {\displaystyle y''\geq G(x,y,y',y'')} " in Annals of the Brazilian Academy of Sciences [pt].
