BUENOS AIRES — Lidia "Taty" Almeida, president of the Mothers of Plaza de Mayo Founding Line, died at age 95 late on Sunday at a hospital in Buenos Aires. Her family stated that she died surrounded by loved ones.

Almeida was born Lidia Stella Mercedes Miy Uranga on June 28, 1930, in Buenos Aires. She worked as a teacher before focusing on raising her family and had three children with her husband, Jorge Almeida.

Her son, Alejandro, was kidnapped by anti-communist paramilitaries in June 1975, nine months before a military junta seized power in Argentina in 1976. Alejandro Almeida was a medical student at the University of Buenos Aires and a member of the People's Revolutionary Army. He has never been found.

The Mothers of Plaza de Mayo organization has held weekly Thursday marches at the Plaza de Mayo outside Argentina's presidential palace since 1977. These marches demand the return of individuals who were disappeared during the 1976-1983 dictatorship. Due to political differences, the organization split into two factions in the 1980s.

Almeida became president of the Founding Line in 2024. The Mothers of Plaza de Mayo stated that Almeida continued her activism until she recently fell ill. She also campaigned on contemporary social justice issues during the final year of her life.

After his kidnapping, Almeida discovered Alejandro's poetry in his diary and published a collection of his work in 2008. The Founding Line released a statement that said, "Thank you for teaching us that to love is to resist, that the only fight we lose is the fight we give up, and that there is no force greater than that of love."
