The Forgotten Mathematical Genius Who Laid the Foundations of Modern Algebraic Geometry
Alexander Grothendieck and his monumental contributions to mathematics
Alexander Grothendieck was a towering figure in the world of mathematics, known for his groundbreaking contributions to the fields of algebraic geometry and topology. His work has had a profound impact on the way we understand and study these subjects, and his influence is still felt today, decades after his passing.
Born in Berlin in 1928, Grothendieck’s early life was marked by tragedy and upheaval. His father, Alexander “Sascha” Shapiro, was a Russian anarchist who fled to France after being imprisoned in the Soviet Union. Grothendieck’s mother, Hanka Grothendieck, was a Jewish journalist who was arrested and killed by the Gestapo during the Nazi occupation of France. Despite these hardships, Grothendieck excelled academically and showed an early aptitude for mathematics. He studied at the University of Montpellier and eventually at the University of Nancy he earned his Ph.D. in 1953.
It was during this time that Grothendieck began to make his mark on the world of mathematics. He developed a number of key ideas and concepts that would later become central to his work, including the notion of a “scheme” and the use of sheaf theory in algebraic geometry. In the late 1950s, Grothendieck became a member of the Institute for Advanced Study in Princeton, where he worked with some of the leading mathematicians of the day, including John von Neumann and Kurt Gödel. It was during this period that he developed his most influential work, the “Elements of Algebraic Geometry.”
“If there is one thing in mathematics that fascinates me more than anything else (and doubtless always has), it is neither “number” nor “size”, but always form. And among the thousand-and-one faces whereby form chooses to reveal itself to us, the one that fascinates me more than any other and continues to fascinate me, is the structure hidden in mathematical things.”

This massive tome, which consists of over 600 pages and contains more than 3,000 definitions and propositions, is widely regarded as one of the most important mathematical texts of the 20th century. It laid the foundations for the modern study of algebraic geometry and has had a lasting impact on the field. In addition to his work on algebraic geometry, Grothendieck also made significant contributions to topology, the study of the properties of geometric objects that remain unchanged under continuous deformations. He developed the concept of “K-theory,” which has become an important tool in the study of topological spaces.
Despite his many achievements, Grothendieck was also known for his unconventional and sometimes controversial views. He was deeply committed to social justice and believed that mathematics should be used for the betterment of humanity. In fact, he once said that
“Mathematics is not just a tool for the natural sciences, but rather a model for the cosmos.”
He was also known for his reclusive nature and his tendency to avoid the spotlight, preferring to focus on his work rather than seeking recognition or accolades. This led some to refer to him as the “hermit of Montpellier.”
Grothendieck’s contributions to mathematics have been recognized and celebrated by the mathematical community. In 1966, he was awarded the Fields Medal, one of the highest honors in mathematics, for his work in algebraic geometry. He was also a recipient of the Crafoord Prize, which is awarded by the Royal Swedish Academy of Sciences to recognize achievements in mathematics and the natural sciences. Despite his many accolades, Grothendieck remained a humble and enigmatic figure, always striving to push the boundaries of what was thought to be possible in the world of mathematics. His legacy will be remembered for generations to come, and his contributions to the field will continue to shape the way we think about and study these subjects for years to come.
