In 1918, López joined the Faculty of Philosophy and Letters of the University of Buenos Aires.[1] Along with other prominent Socialists like Fenia Chertkoff and her sister Mariana Chertkoff, Alicia Moreau, Sara Justo, and Carolina Muzzilli, López advocated for schools to encompass feminist issues in their curriculum. Specifically, she advocated for classes on hygiene, sex education, citizenship and the responsibilities of voting, as well as horticulture and gardening.
