Born on 23 January 1892 in Paris, as the youngest of the four children of Adolphe Bloch, a doctor, and his wife Noémie Allatini.

At the latter school, Bloch was classmates with a Russian student named Mikhail Gurevich, who would later become instrumental in the creation of the MiG aircraft series.

In 1916, with Henry Potez and Louis Coroller, he formed a company, the Société d'Études Aéronautiques, to produce the SEA series of fighters.

[citation needed] In 1936, the company was nationalized as the Société Nationale de Constructions Aéronautiques du Sud Ouest (SNCASO).

In 1944, the Nazis deported Bloch to the Buchenwald concentration camp,[2] as punishment for refusing to co-operate with their regime.

This name derived from 'Chardasso', the nom de guerre used by his brother, General Darius Paul Bloch, when he served in the French Resistance.

In 1919, Bloch married Madeleine Minckès, the daughter of a wealthy Jewish family of furniture dealers.

In The Adventures of Tintin book Flight 714 to Sydney, Dassault is parodied as the aircraft construction tycoon Laszlo Carreidas – "the millionaire who never laughs" – who offers Tintin, Captain Haddock and Professor Calculus his personal jet, the Carreidas 160, to travel to Sydney.
