Introduction:
Lars Ahlfors, a mathematician famed for his groundbreaking work in complex analysis and Riemann surfaces, became one of the first two recipients of the prestigious Fields Medal in 1936. While the recognition boosted his confidence, it was the turbulent years that followed—marked by war, personal sacrifice, and an improbable journey to safety—that truly tested his resolve. His story is one of resilience, wit, and an extraordinary blend of intellectual and human perseverance, culminating in an unexpected encounter with his own Fields Medal in a pawn shop.
A Historic Award Under Harrowing Circumstances:
In 1936, Lars Ahlfors was shocked to learn that he would be awarded one of the first two Fields Medals ever presented at the International Congress in Oslo. Although the honor was not as renowned as it is today, it marked a significant moment in Ahlfors’ life, solidifying his place in the mathematical community. As he later reflected, receiving the medal "did much to increase the confidence I felt in my work." Little did he know that the years ahead would test both his intellectual and personal endurance in ways he could never have imagined.
The War Years and the Move to Sweden:
As Europe was ravaged by the outbreak of World War II, Ahlfors' life would take a dramatic turn. His family moved to Sweden, but Ahlfors, remaining in Helsinki, found himself in the midst of an increasingly dire situation. With universities and libraries closed due to the war, Ahlfors continued his research under extreme conditions—conducting much of his work within air raid shelters. His commitment to mathematics during these difficult times demonstrated the strength of his character and his dedication to his field, even as war surrounded him.
A Bold Decision and a Pawned Medal:
In 1944, as Finland's situation grew even more perilous, Ahlfors was offered a professorship at the Polytechnic in Zurich. Given his precarious health, he was allowed to reunite with his family in Sweden. However, the journey out of Finland was far from easy. Ahlfors could only carry a mere 10 kroner with him, so in an act of desperation, he smuggled his beloved Fields Medal and pawned it to raise money for the journey.
Ahlfors later recalled with a wry smile, “I am sure it is the only Fields Medal that has ever been in a pawn shop.” After he managed to get some money, kind-hearted people in Sweden helped him retrieve the medal. Despite the struggles of war and displacement, Ahlfors' devotion to his work, and his unwavering sense of humor, remained intact.
A Journey of Hope to Switzerland:
Ahlfors' path to Zurich was as difficult as it was improbable. He boarded a plane from Stockholm to Prestwick, Scotland, on a freezing night in March 1945. The unpressurized plane was equipped with oxygen masks, and all passengers wore life jackets, as they journeyed over icy waters. Upon reaching Glasgow, Ahlfors continued his journey by train to London, crossing the English Channel, traveling through France, and finally reaching Switzerland. The long and arduous trip was filled with uncertainty, but Ahlfors remained hopeful, driven by the desire to reunite with his family and continue his academic work.
Unexpected Disappointments Upon Arrival:
Once in Zurich, Ahlfors was greeted with the realities of post-war academia. Despite his world-renowned expertise, his first disappointment came when he learned that he had been assigned to teach Descriptive Geometry, a subject that seemed out of place in the Swiss university curriculum. His second, and perhaps more humorous, disappointment was learning that he would have to teach it from 7 to 9 in the morning. As a mathematician who had already made significant contributions to the field, Ahlfors found these assignments to be less than ideal, yet his ability to find humor in the situation shone through.
Ahlfors’ journey, filled with hardship, sacrifice, and determination, serves as a testament to the resilience of the human spirit in the face of adversity. His remarkable story is not just one of mathematical achievement but also of personal endurance and wit. And, of course, his Fields Medal—pawned and reclaimed—remains a symbol of the extraordinary life he led during a time of unprecedented challenges.
