Ivone Guimarães

Ivone Guimarães Batista Lopes (Pitangui, 15 June 1908 - 9 March 1999) was a Brazilian professor, suffragist and activist. She was one of the first women to vote in Brazil. She was the daughter of Vital Pereira Guimarães and Amélia Lobato. She married Engenheiro Alício Batista Lopes, and they had several children: Alício, Paulo de Tarso, Francis, Patrícia Catarina, Magnus and Ruimar. On 17 October 1928, she spoke up alongside Miêtta Santiago who challenged the constitutionality of the ban on women voting in Brazil, stating that it breached Article 70 of the country's Constitution, dated February 24, 1891, which was then in force. This action led Guimarães to become one of the pioneers in exercising the right to vote in her country.
