A doctor, gynaecologist and professor who created the Fine Arts and Crafts Academy for Women in 1885, together with Clotilde Cerdà, where she taught domestic hygiene. In 1882, she was the first woman medicine graduate to exercise her profession and the second, after Maria Elena Maseras, to obtain her doctorate, with her thesis On the need for a new approach to women's hygiene-moral education. The text criticised the use of corsets for medical purposes, as it put women's health at risk. She specialised in gynaecology and paediatrics. She was also the first women to be a member of the Société Française d’Hygiène. For 25 years she ran a medical surgery on Rambla de Catalunya. And she combined medicine with teaching, writing informative texts on improving the lives of mothers and the dangers of sexually transmitted diseases.
