Hermitte studied at the Faculty of Philosophy and Letters of the University of Buenos Aires.
After that she won a scholarship from the National Scientific and Technical Research Council, which was directed by Bernardo Houssay.
In 1958 Hermitte moved to the University of Chicago in the United States, where she assisted with the social systems courses.
The following year she was sent to Mexico together with linguist R. Radhakrishnan and interpreter Alberto Méndez Tobilla to conduct field work with the Mayan community of Pinola, Villa Las Rosas in the state of Chiapas.
