    Fernand HOLWECK, Né Le 21 Juillet 1890, À Paris, Et Mort, À Paris, En

    Fernand HOLWECK, né le 21 juillet 1890, à Paris, et mort, à Paris, en décembre 1941, assassiné par la Gestapo en raison de ses activités de résistance, était un universitaire et un physicien-chercheur réputé dans le domaine des rayons X. Fernand Holweck était le fils d’un sculpteur parisien issu d’une famille alsacienne et catholique émigrée en France. Habitant le 14e arrondissement, il a fréquenté l’école Lavoisier puis, dès 1907, l’École de physique et de chimie industrielles de la Ville de Paris dont il est sorti major de sa promotion, en 1910. Fernand Holweck s’était marié en 1923 avec Jacqueline, une jeune femme d’origine corse. Ils eurent un fils, Jacques, et deux filles, Mireille et Gabou (sans doute un surnom). Holweck était entré à au Laboratoire Curie de l’Institut du Radium, dirigé par Marie Curie, en 1912, à 22 ans, comme préparateur particulier de la directrice du laboratoire puis assistant. Il était ensuite devenu chef de travaux, maître de conférences, maître de recherches et enfin, un grade alors rarement attribué, directeur de recherches au CNRS. Il y devint rapidement un spécialiste de l’étude des radiations existant dans l’ultra-violet lointain et des rayons X, dont il apprit à fournir des doses connues en intensité et en longueur d’onde. Ses travaux lui permirent d’obtenir le titre de docteur ès sciences à la faculté des sciences de Paris, en 1923. Ses recherches le conduisirent aussi à travailler constamment sur la réalisation de vides de plus en plus poussés, à étudier les effets biologiques des rayons X et à contribuer au développement de la radiologie.

In this context, we present the activities of French scientists and scientific institutions during the period. We focus on the creation in 1887 of the “commission d’examen des inventions intéressant l’armée” and the contribution of the mathematician Paul Painlevé; the activities of some scientists contributing to the “war effort” despite their internationalist convictions: Aimé Cotton, Weiss, de Gramont and Chrétien, Langevin, Perrin, Marie Curie and Regaud; innovative research and development on scientific instruments in various disciplines, such as communications and radiotelegraphy, optics, chemistry, medicine and their applications; the contributions of the « grandes écoles parisiennes », for instance, the School of Industrial Physics and Chemistry; the impact of the WWI on the organisation of the French research and the creation of new research institutions, and the consequences of the loss of numerous young scientists. Key words: World War I, French scientists, inventions, French army.

    Marie Sklodowska Curie: The Woman Who Opened The Nuclear Age by Denise Ham A new look at a revolutionary scientist’s passion for truth, and how she inspired a generation of Americans. n my quest to examine the life of Marie Curie, I had the good for- Itune to rediscover her life’s work, particularly her discovery of poloni- um and radium, and her great dis- covery concerning the nature of the atom. In this journey, I was happy to become intimately aware that dis- covery itself, is an issue of passion. It surprised me considerably that my understanding of her work grew enormously, because I simply loved trying to understand that which she discovered. Since my formal educa- tion is more than bereft, especially in science, I think that I am fortunate in being able to discover in myself that very passion for knowledge which drives the creative individual to make critical discoveries that transform the physical universe. I have many peo- ple to thank for helping me in this project, which took more than a year; foremost, I wish to thank Madame Marie Sklodowska Curie, and say that her life is an inspiration which I AIP Niels Bohr Library have loved.
