Agnès Humbert was born in 1896 in Dieppe, and married the artist Georges Sabbagh in 1916. They had two sons. Agnès continued her studies in art history, but they were divorced in 1934. In 1936 she published an influential book Louis David: peintre et conventionnel, which made her reputation as an art historian. The following year she was recruited to the staff of the newly created Musée National des Arts et Traditions Populaires, a sister institution to the Musée de l'Homme. After the war she refused on principle to return to the post from which she had been sacked, but continued to write books on art until her death in 1963.

Barbara Mellor is a translator specialising in the fine and decorative arts, art history, architectural history, fashion and design. Her most recent projects include The House of Dior and The Society Portrait (both Thames & Hudson), and a series of exhibition catalogues for individual contemporary artists. She now divides her time between the Scottish Borders and the Aveyron.

In the summer of 1940, as the German Occupation tightened its grip on Paris, Agnès Humbert helped to establish one of the first resistance cells. Within a year the group was publishing a news bulletin, helping allied airmen escape and passing military information back to London. Then came the catastrophe of betrayal, followed by arrest and interrogation, imprisonment and trial and, for Agnès, deportation to slave labour camp in Germany. Résistance is the secret journal of a woman who never gave up hope.

'Sober and testifying, sardonic and humorous ... A beautiful and powerful work of literature'

'Humbert's memoir bears witness to innumerable horrors, presented here with a pugnacious courage ... What makes this horrific account so affecting is Humbert's sense of humour, her indomitable refusal to submit'

'An astonishing work, almost unbearable to read in places, yet ultimately inspiring ... A remarkable book by a remarkable and brave woman'

'Her book adds to the small record of how the human mind can preserve the heart and soul intact against all attempts to annihilate it'

'Agnès Humbert bears devastating witness to her time ... An insider's account of the germination of the French Resistance' William Boyd
