1. Mastering Classical Greek by Age Six

Neumann's prodigious talent was evident early on. While most children were learning basic skills, he was already able to converse in Classical Greek and Latin. His affluent parents were astounded by his ability to memorize extensive texts in mere moments, leaving a lasting impression on family gatherings. Whether or not photographic memory exists, Neumann's exceptional recall suggests he might have possessed something akin to it.

His fascination with numbers led him to perform complex calculations in his mind, such as dividing 8-digit figures effortlessly. While many struggle with high school algebra, he was already adept in calculus by the age of eight. The transition from memorizing random addresses to engaging in sophisticated discussions about ancient governance or solving intricate mathematical problems was seamless for him.

2. A Terrible Driver

In stark contrast to the archetype of a socially awkward scientist, Neumann was known for his vibrant personality—and his reckless driving. His penchant for hosting lively gatherings and blasting German music was overshadowed only by his notorious driving skills. He was involved in numerous car accidents throughout his life, frequently necessitating the purchase of new vehicles.

Despite his brilliance in mathematics, he struggled to pass his driver's license test, leading him to resort to bribery. According to his daughter, no amount of practice improved his driving ability, and a particular intersection in Princeton became infamous for the number of accidents involving him.

3. Simultaneous Studies Across Borders

Neumann's family did not initially view mathematics as a promising career choice. His father, a banker, hoped his son would pursue a more traditional path. Neumann attended the prestigious Lutheran Gymnasium, later studying chemical engineering at the Swiss Federal Institute in Zurich, all while earning a Ph.D. in mathematics from the University of Budapest.

By the age of 21, Neumann's mathematical prowess was widely acknowledged, and at 23, he became the youngest lecturer in the history of the University of Berlin. His multifaceted interests often left students both confused and inspired, as they witnessed the flow of ideas from his brilliant mind.

4. The 'Martian' at Princeton

Neumann's journey to America was marked by the upheavals of the early 20th century, including the rise of fascism. Invited to Princeton in 1929, he quickly became a faculty member and later the youngest professor at the Institute for Advanced Study.

His vibrant personality helped him navigate social circles filled with European émigrés who had fled oppressive regimes. These individuals, often referred to as 'Martians' due to their foreign ideas, found camaraderie in their shared beliefs in progress and human creativity.

5. A Childhood Game with Profound Implications

Neumann's favorite childhood game, Kriegsspiel, served as a precursor to his later work in game theory. Originally designed as a military training exercise, it reflected the principles of strategic decision-making that would later become central to his academic contributions.

In his 1928 paper "Theory of Parlor Games," Neumann introduced the "Minimax theorem," laying the groundwork for modern game theory. His collaboration with Oskar Morgenstern in 1944 produced "Theory of Games and Economic Behavior," a seminal text that bridged economics and game theory.

6. Involvement in the Manhattan Project

As tensions escalated in the lead-up to World War II, Neumann's interests shifted towards military applications. He contributed to the Manhattan Project, specifically the development of the implosion method for atomic bombs.

His work on the "Fat Man" bomb was pivotal, and he played a role in selecting targets and estimating potential casualties. His military engagements reflected a deepening commitment to applying his mathematical skills in real-world scenarios.

7. Pioneering the First Programmable Computer

Amidst the Cold War, Neumann recognized the potential of computers in military strategy and problem-solving. He laid the foundations for what is now known as the "von Neumann architecture," which allows computers to store and retrieve data simultaneously.

In 1945, he was instrumental in the development of ENIAC, the first programmable computer. His efforts to promote collaborative innovation in computing set the stage for future advancements.

8. Environmental Awareness Ahead of His Time

Despite his association with certain right-wing organizations, Neumann possessed a nuanced understanding of environmental issues. He warned about the potential consequences of industrial activity on the planet's climate, advocating for the use of computers in environmental forecasting.

In 1950, his work led to the establishment of computerized weather forecasting at Princeton, reflecting his forward-thinking approach to technology and nature.

9. Final Days Surrounded by Military Personnel

In 1956, as his health deteriorated, Neumann was surrounded by military officials in a hospital room. Aware of his legacy and the secrets he held, these officers ensured that sensitive information remained confidential during his final days.

Even as cancer ravaged his body, Neumann's intellectual curiosity remained alive. He would frequently request his daughter to test him on basic mathematics, clinging to the skills that had defined his extraordinary life.
