  This article explores how mathematics, specifically statistics and probability, were manipulated in Nazi Germany to promote racist ideologies and justify discriminatory policies. It examines how seemingly objective mathematical concepts were twisted and selectively applied to create a false sense of scientific backing for eugenic programs and the persecution of minorities. By focusing on skewed data and misrepresenting statistical concepts, the Nazi regime aimed to convince the public of the inferiority of certain groups, thereby normalizing and legitimizing their horrific actions. The article serves as a warning about the potential for mathematical tools to be misused in the service of dangerous ideologies.

  Michael J. Barany's 2017 Undark Magazine article, "A Math Lesson From Hitler’s Germany," delves into the complex and often paradoxical relationship between mathematics, politics, and ideology during the Nazi regime. Rather than portraying a simplistic narrative of intellectual suppression, Barany illustrates the nuanced ways in which mathematics was both instrumentalized and contested within the Third Reich. He focuses on the career and experiences of Ludwig Bieberbach, a prominent mathematician known for his contributions to complex analysis and geometry, who became an ardent supporter of National Socialism. Bieberbach attempted to establish what he termed "Deutsche Mathematik," or German mathematics, a racially inflected approach to the discipline that sought to distinguish itself from what he perceived as the overly abstract and "Jewish" nature of modern mathematics.

  Barany meticulously details Bieberbach’s efforts to align mathematics with Nazi ideology, including his attempts to infuse racial theories into mathematical pedagogy and research. Bieberbach promoted the idea that different races possessed inherent mathematical styles, arguing that "German" mathematics was intuitive, visual, and grounded in physical reality, while "Jewish" mathematics was overly abstract, formalistic, and detached from the real world. He used these purported distinctions to justify the exclusion and persecution of Jewish mathematicians from German universities and academic societies.

  The article further explores the reactions and resistance to Bieberbach’s ideological project within the mathematical community. While some mathematicians embraced or passively accepted Deutsche Mathematik, others actively opposed it, arguing that mathematics was a universal and objective discipline transcending racial and political boundaries. Barany highlights the debates and controversies that arose surrounding this issue, demonstrating that the mathematical landscape of Nazi Germany was not monolithic but characterized by a complex interplay of conformity, dissent, and opportunistic maneuvering.

  Barany’s analysis extends beyond the purely intellectual realm to examine the practical implications of Deutsche Mathematik. He discusses how these ideologically driven pronouncements impacted the careers and lives of mathematicians, both Jewish and non-Jewish, affecting hiring decisions, research funding, and the overall direction of mathematical inquiry in Germany. The article also touches on the international ramifications of this politicization of mathematics, illustrating how it influenced collaborations and exchanges between German mathematicians and their colleagues in other countries.

  In conclusion, "A Math Lesson From Hitler’s Germany" offers a nuanced and historically grounded exploration of the entanglement of mathematics with Nazi ideology. It underscores the dangers of politicizing scientific disciplines and highlights the importance of upholding the principles of intellectual freedom and objectivity in the face of ideological pressures. Barany’s meticulous research and detailed narrative shed light on a complex and often overlooked chapter in the history of mathematics, providing valuable insights into the interplay between science, politics, and ideology in a time of profound social and political upheaval.
