Balint was born Mihály Maurice Bergsmann, the son of a practising physician in Budapest. It was against his father's will that he changed his name to Bálint Mihály. He also changed religion, from Judaism to Unitarian Christianity. During World War I Bálint served at the front, first in Russia, then in the Dolomites. He completed his medical studies in Budapest in 1918. On the recommendation of his future wife, Alice Székely-Kovács, Bálint read Sigmund Freud's "Drei Abhandlungen zur Sexualtheorie" (1905) and "Totem und Tabu". He also began attending the lectures of Sándor Ferenczi, who in 1919 became the world's first university professor of psychoanalysis.
