Eugenio Calabi (born May 11, 1923 – died September 25, 2023) was an American mathematician. He was born in Italy. He was a special professor of mathematics at the University of Pennsylvania. Calabi was an expert in differential geometry. This is a field of mathematics that studies shapes and spaces. He also worked with partial differential equations. These are special math problems.

Early Life and Moving to America
Eugenio Calabi was born in Milan, Italy, on May 11, 1923. His family was Jewish. In 1938, his family had to leave Italy. This was because of unfair laws against Jewish people. They moved to the United States in 1939. His sister, Tullia Zevi, became a well-known journalist.
Academic Journey and Career
In 1939, when he was just 16, Calabi started college. He studied chemical engineering at the Massachusetts Institute of Technology (MIT). His studies were paused in 1943. He was drafted into the U.S. military during World War II.
After the war, Calabi returned to MIT. He finished his bachelor's degree in 1946. He then earned a master's degree in mathematics. This was from the University of Illinois Urbana-Champaign in 1947. He got his PhD (a very high degree) in mathematics in 1950. This was from Princeton University. His main teacher was Salomon Bochner.
Calabi began his teaching career in 1951. He taught at Louisiana State University. In 1955, he moved to the University of Minnesota. He became a full professor there in 1960. In 1964, Calabi joined the math team at the University of Pennsylvania. He became a special professor there in 1968. He retired in 1994. In 2014, the university gave him an honorary science degree.
Awards and Recognition
Eugenio Calabi received many honors. In 1982, he was chosen for the National Academy of Sciences. This is a very important group of scientists. He won the Leroy P. Steele Prize in 1991. This award recognized his important work in geometry. In 2012, he became a fellow of the American Mathematical Society. In 2021, he received a special award from Italy.
Calabi married Giuliana Segre in 1952. They had a son and a daughter. He lived to be 100 years old. He passed away on September 25, 2023.
Key Discoveries in Mathematics
Calabi made many important contributions to differential geometry. This area of math studies curved spaces. One of his most famous ideas is the Calabi conjecture. This was a math problem he proposed. It was later solved by another mathematician, Shing-Tung Yau. This led to the idea of a Calabi–Yau manifold. These are special shapes used in physics, like in string theory.
He also worked on other math topics. These included the Calabi flow and the Calabi triangle. His work helped change how mathematicians understood geometry. He was very proud of his work on "Improper affine hyperspheres."
