Bertha Lutz (August 2, 1894 – September 16, 1976) was a Brazilian
zoologist, politician, and diplomat. She became a leading figure in the Pan-American feminist and human rights movements, and was instrumental in gaining
women's suffrage in Brazil. In addition to her political work, she was a naturalist at the
National Museum of Brazil, specializing in
poison dart frogs. Her collections were destroyed in September 2018, when a fire devastated most of the museum's collections.
