Helena Antipoff

Helena Wladimirna Antipoff (25 March 1892 – 9 August 1974) was a Russian-born Brazilian psychologist. Born in Grodno in what is now Belarus to an aristocratic family, they moved from the Russian Empire to Paris due to increasing social unrest. While there, Antipoff earned a bachelor's degree from the University of Sorbonne in 1911 and interned under Théodore Simon in Alfred Binet's laboratory. Antipoff spent the next four years at the Jean-Jacques Rousseau Institute to study under Édouard Claparède, graduating with a degree in educational psychology. While there, she became a proponent of the active school style of education, focusing on autonomous learning for students.

Antipoff moved back to Russia in 1916 to take care of her father, who had been injured in World War I. She stayed in Russia until 1924, marrying Victor Iretzky and having a son, Daniel Iretzky Antipoff, during that time. In 1924, she published an article about the cognitive abilities in children, which the Soviet regime claimed was trying to push upper-class superiority; the family fled to Germany the following year as a result. After her death in 1974, the Helena Antipoff Foundation was established, which continues her work. Minas Gerais Governor Milton Campos said of her and of the foundation: "She planted ten thousand seeds in our wilderness. All teachers and students whose lives she touched will now continue her work."
