Born in Petrograd, Belinky came to Brazil with her family when she was ten years old, fleeing from the civil wars in the then Soviet Union.

At twenty she enrolled at the Philosophy course of Faculdade São Bento, but she abandoned it then when she married the doctor and educator Júlio Gouveia in 1940.

In 1948, Belinky begins to work adapting translating and creating children's plays for São Paulo city government in partnership with her husband.

The success of this work was definitive for the budding writer's career: the couple is asked to have a fixed program on the TV network.

Meanwhile, Tatiana Belinky receives her first award as a writer, as well as becoming president of CET (São Paulo State Commission for Theatre).
