In the first chapters, we learn about her ancestors and family. Yvonne Choquet-Bruhat was born as the second of three children on December 29, 1923 in Lille, a city in the very north of France. Her father was Georges Bruhat, and her mother was Berthe Hubert. When Yvonne was two years old, the family moved with their daughters Jeanne and Yvonne to Paris. Her brother François came into the world a few years later. Georges Bruhat worked as a physics professor at the University of Lille, and later at the Sorbonne in Paris. He became vice-director of the École Normale Supérieure (ENS) in the mid-1930s. Georges Bruhat was a loving father and family man. He was organized and structured his days in a way that maximized both the time spent with his family and the time spent at work. Despite all his duties, he always found time to sit down with his children to study, do homework, or discuss science. Berthe Hubert taught literature and philosophy at the high school level and higher (Première Supérieure), first in Chambéry, then in Poitiers, Lille, and Paris. She is characterized as a woman who did not hide her thoughts and had a deep understanding of human problems. Both Yvonne’s parents cared well for their children and supported them in their endeavors. Georges Bruhat and Berthe Hubert provided their children with an intellectual family environment, which was augmented by nannies, as well as relatives and friends of the parents who would come to stay with them. They took family vacations in the Alps and at the Mediterranean, and spent time at their house in Dammartin (near Paris). This comfortable lifestyle was quite different from how their ancestors lived. Some of her father’s ancestors, including her great-grandfather, worked breaking stones for roads. To escape this hard life, the next generation had military careers or became teachers. Her mother’s family members were mainly farmers for several generations. Yvonne’s maternal grandfather became a teacher who was able to send both of his children to universities. Yvonne Choquet-Bruhat went through the rigorous French school system. One has to remember that at the time boys and girls were schooled separately. Teachers had a lot of influence. Already as a girl, Yvonne cultivated an independent mind and made friends for life. For a while, life was good. The author describes pleasures and problems throughout those years and names a subchapter “The Happy Years.” This happiness would end in 1939 with the beginning of World War II and the German attack on France on May 10, 1940. Paris fell in June of that year, and France signed an armistice that left Paris in the occupied zone and the southern part of France under the Vichy Regime. Georges and Berthe tried to protect their children as much as possible during this dark period, sending them to stay with their uncle in Poitiers in 1939. Just before the Germans invaded Paris, Georges Bruhat departed for Bordeaux with his physics laboratory. Yvonne’s mother and grandmother then joined the children in Poitiers and they all headed for Bordeaux as well. It was a journey with interruptions, where at one point Yvonne found herself separated from the others, but finally the family was reunited in Bordeaux. Later, Georges Bruhat decided to go back to Paris and use his position of leadership at ENS to protect not only his laboratory from the Germans, but more importantly, to protect his students from the Nazis. He ended up helping many Jews and members of the Resistance travel to unoccupied France, where he found refuge for them. From there they could leave for Britain, where many of them joined the Allies. On June 6, 1944 (D-Day), the …
