The Contribution of Women in the Development of Quantum Theory.: "Throughout much of the story, Anonymous was always a woman." (Virginia Woolf) ... Texts by Bruno Del Medico in English. (ING))

Science, for many centuries, has been a male-dominated realm. Not because of a lack of talent or insight on the part of women, but because of social and cultural structures that systematically excluded them. This phenomenon is particularly evident in the history of physics, and even more so in the development of quantum theory. What would have become of modern science if the names of these women had been recognized on par with those of their male colleagues? This is a question that our time can no longer ignore.
An emblematic example of this historical invisibility is the story of Lise Meitner, an extraordinary physicist who contributed to the discovery of nuclear fission. It was 1938 when Otto Hahn, her longtime colleague, received sole credit for this discovery, subsequently earning a Nobel Prize. Lise Meitner, on the other hand, was relegated to the margins of scientific history, despite her fundamental calculations that enabled the understanding of the fission process. "A mind that never lost its clarity," was how Albert Einstein described her, but that was not enough to secure her recognition. Lise Meitner, who was Jewish and had to flee Nazi Germany, pursued her work in an environment that was hostile to both her gender and her identity.
The story of these women is not only scientific, but deeply cultural. Even in the world of literature, the issue of female invisibility in the intellectual professions has been forcefully raised. Virginia Woolf, in her famous essay "A Room of One's Own" (1929), reflected on what a young woman might have made of Shakespeare's genius had she lived in his time. Woolf imagined that this figure, "Judith Shakespeare," would never have had the opportunity to emerge. The same image applies perfectly to science: how many women have had the genius and lucidity of a Marie Curie, but never had access to the resources, laboratories, or collaborative networks needed to express themselves?
The case of quantum theory is particularly interesting. This branch of physics, which has transformed our understanding of the subatomic world, developed thanks to a community of brilliant minds, many of them women. However, only a few names have remained etched in the historical narrative. One of these is that of Maria Goeppert Mayer, the second woman in history to win a Nobel Prize in physics (1963), for her model of the atomic nucleus. For years, Maria worked under precarious conditions, often without receiving an adequate salary, limited by prejudice against women "scientists' wives." Nevertheless, her contribution was fundamental to modern physics.
In addition to individual examples, there is a broader reflection on the "why" of this invisibility. Historically, women's research was published under the names of their husbands or male colleagues, making it complicated to identify their real contribution. In many cases, women were even prohibited from entering universities or laboratories. A symbolic example is that of the Royal Society of London, one of the most prestigious scientific institutions in the world, which accepted the first woman as a member only in 1945, nearly three centuries after its founding.
It is not surprising, then, that many of these women have found marginal space even in popular and academic memory. Even today, their stories often remain unknown. Yet, their work continues to profoundly influence the way we see the world. Quantum physics would not be what it is without the minds of these women.
