Afanasyeva was born in Kiev in the Ukraine. After her father died she was brought up by an uncle in St Petersburg, Russia, where she attended a women's pedagogical school and a Women's College. In 1902 she transferred to Göttingen, where she met Ehrenfest. The couple got married in 1904. She collaborated closely with her husband, more famously on their classical review of the statistical mechanics of Boltzmann ^ . She published many papers on various topics such as randomness ^  and entropy, and teaching pedagogy ^ .
