Biography
Michele Angelo Besso was born on May 25, 1873, in Zurich's District 8, into a Swiss-Italian Jewish family. He attended ETH Zurich, the Swiss Federal Institute of Technology, studying engineering, and also went to the University of Zurich. During his student years, Besso met Albert Einstein through social and academic circles in Zurich, forming one of the most impactful friendships in modern physics.
Besso spent much of his career as an engineer and eventually got a job at the Swiss Patent Office in Bern, working alongside Einstein in the early 1900s. They had ongoing discussions about physics and philosophy during this time. Einstein specifically mentioned Besso in his famous 1905 paper on special relativity, calling him his closest friend and intellectual partner. This is one of the few personal acknowledgments Einstein ever made in his scientific works.
Besso played a key role in Einstein's special theory of relativity as a critical thinking partner, although not as a co-author. Besso had a broad and curious mind that included engineering, mathematics, and philosophy, and Einstein valued his ability to engage with complex problems. Their letters, which they exchanged for many years after their Bern days, show a relationship full of mutual respect and intellectual engagement.
After leaving Bern, Besso continued to work as an engineer and stayed in touch with Einstein through letters. They wrote to each other for over fifty years about physics, philosophy, personal matters, and the turmoil of two world wars. Besso passed away in Geneva on March 15, 1955, just weeks before Einstein. Upon learning of his friend's death, Einstein wrote to Besso's family, saying that losing his old friend reminded him that his own time was near. He noted that for a physicist, the differences between past, present, and future are just persistent illusions.
Before Fame
Michele Besso grew up during a time of rapid scientific and technological change in Europe. In the latter half of the nineteenth century, Switzerland was emerging as a hub for engineering education and precision industry, with places like ETH Zurich attracting ambitious students from across Europe. Besso's enrollment at ETH Zurich put him right in the middle of this intellectual scene, where he received rigorous training in mathematics and the physical sciences as classical physics was nearing its limits and new theories were starting to emerge.
His time as a student in Zurich was crucial for his future importance. His early friendship with Einstein, who was also a student in the city, marked the beginning of a lifelong intellectual partnership. Though Besso chose a practical career in engineering rather than academic research, his wide-ranging intellectual interests and genuine curiosity made him the perfect conversational partner for one of the era's most original scientific minds. His rise to prominence was not through independent discovery, but through his sustained and serious engagement with ideas.
Key Achievements
- Named personally by Albert Einstein in the acknowledgments of the 1905 special relativity paper, a rare distinction in Einstein's body of work
- Maintained a decades-long intellectual correspondence with Einstein that provides historians with insight into the development of modern physics
- Contributed as an engineering professional in Switzerland while sustaining serious engagement with theoretical physics beyond his formal field
- Helped Einstein think through conceptual problems related to space, time, and electrodynamics during their shared years at the Bern Patent Office
Did You Know?
- 01.Einstein's 1905 special relativity paper is almost unique among his major works in containing a personal acknowledgment, and the only person named is Michele Besso.
- 02.Besso and Einstein both worked at the Swiss Patent Office in Bern at the same time, and it was during walks and conversations there that Einstein worked through key conceptual problems in his theory of relativity.
- 03.The correspondence between Besso and Einstein spanned more than fifty years and has been studied by historians of science as a valuable record of Einstein's evolving thinking.
- 04.Upon learning of Besso's death in March 1955, Einstein wrote to Besso's family invoking his belief that the separation between past, present, and future is a stubborn illusion, a reflection of his lifelong views on the nature of time.
- 05.Einstein died less than six weeks after Besso, in April 1955, making their deaths remarkably close together after a friendship that had lasted over half a century.
