On the outbreak of war, Pierre became an interpreter for the British army.
He was arrested in December 1941 because of his Jewish ethnicity, but was released in March 1942, on the intervention of his wife.
The family decided to leave for the free region of France.
At Toulouse, Annette succeeded in passing her PCB exams, the first stage in a medical qualification.
Along with her father, she joined the Resistance.
After a time, the Germans invaded this region of France too.
Pierre was arrested again, this time along with his daughter, and she was imprisoned at Fort de Romainville.
