Early life Adelaide Augusta Fernandes Estrada was born on 29 September 1898 in the Porto parish of Vitória. She went to school at the Liceu Alexandre Herculano in Porto. Following her father's death in 1913, she worked at a hospital part-time in order to be able to complete her school studies.

As a student, she was invited to work at the Institute of Histology and Embryology of FMUP in 1922.

She stayed there until the Centre closed after Salazar's death in 1946. Her research at FMUP and at the Centre for Microscopic Studies led to a large body of journal articles, including "Meningeal Syndromes and Abnormal Acute Meningitis", "Questions of Hematological Nomenclature" and "The Hematological Indexes Have No Diagnostic Value".
