As early as 1935, leading intellectual women in El Salvador, including Guzmán, Tránsito Huezo Córdova de Ramírez, Claudia Lars, Matilde Elena López, María Loucel, Ana Rosa Ochoa and Lilian Serpas, were broadcasting programs over El Salvador's first private radio station, La Voz de Cuscatlán discussing social and political issues.
[1] In 1945, Guzmán and Ana Rosa Ochoa founded the journal Tribuna Femenina (Feminist Tribune) as the official voice of the Association of Democratic Women of El Salvador.
[5] When the LFS received their full charter in 1948, the organization began looking at the current laws and how to better protect women and children's socio-economic, civic and political rights.
[6] In 1950, Guzmán and the LFS pressed Reynaldo Galindo Pohl, head of the Constituent Assembly to grant women the right to vote.
[4] In the same year, the Tribuna Femenina changed its name to Heraldo Femenino and widened its scope to include economic parity for women.
