Born into a family of physicians, Braunberger at the age of seven was already determined not have the same life as his father, and not to take up medicine as a career.

After the First World War, at the age of 15, he produced and directed his first film: Frankfurt in Germany.

Wanting to direct and produce in France, he returned to Paris and got to know Jean Renoir, with whom he worked on Avec qui il va tourner, The Whirlpool of Fate, Nana and Tire-au-flanc.

He renovated the lobby, created 450 seats, and installed Western Electric projectors and sound equipment.

[1] At the end of the Second World War, Braunberger transformed a local Gestapo office into the Cinema Studio "Studio Lhmond", which he used to discover new talents of the "nouvelle vague", including Jean-Pierre Melville, Jean-Luc Godard and Alain Resnais.
