COMMENT VISIONNER CE FILM ?

Lors de la capitulation de 1940, un fantassin français se donna la mort dans le village vosgien d’Housseras. Quatre ans après, il fut identifié comme "soldat Doblin, Vincent". Mais sa véritable identité, sa vie et son histoire ne seront découvertes que bien plus tard : il s’agissait du mathématicien Wolfgang Döblin, l’un des fils de l’écrivain allemand Alfred Döblin ("Berlin Alexanderplatz") qui, juif et antinazi, avait dû fuir l'Allemagne avec sa famille en 1933. Naturalisé en 1936, Wolfgang Döblin poursuivra pendant son service militaire et dans les conditions extrêmes de la "drôle de guerre" ses recherches sur les "mouvements aléatoires" en probabilités.
Ses derniers manuscrits ne pourront être étudiés qu’en 2000. Ses travaux, très en avance sur leur temps, le placent aujourd’hui parmi les grands innovateurs du calcul probabiliste moderne, ces "mathématiques du hasard".

When France surrendered in 1940 and German soldiers showed up in the Vosgian village of Housseras, an unknown French foot soldier burned his papers and killed himself in a farmer's barn. Four years later he was identified as "soldat Doblin, Vincent". In fact, he was none other than the mathematician Wolfgang Doeblin, son of the famous German novelist Alfred Döblin ("Berlin Alexanderplatz") who was forced to flee Nazi Germany with his family in 1933. A French citizen since October 1936, Wolfgang Doeblin carried on his research into probability theory during his military service and even during the hardships of the "Phoney War" in the winter of 1939-40. In February 1940, four months before his death at the age of 25, he sent his most important manuscripts ("About the Kolmogoroff Equation") as a "sealed envelope" to the Academy of Science in Paris, where they were kept in safe custody for 60 years. Wolfgang Doeblin's short and dramatic life story, almost forgotten, was finally brought into the limelight when the "sealed envelope" was opened in May 2000. Far ahead of their time, his groundbreaking contributions to the theory of random processes place Wolfgang Doeblin among the major innovators of probability, the "mathematics of randomness". Mathematical models for evaluation of chances and risks went on to gain major importance in numerous domains of modern science, in everyday life and especially in contemporary financial mathematics.
