Origin
Meaning and origin of Caccioppoli
The surname Caccioppoli originated in Italy, likely in the region of Campania during the medieval period. The name is believed to be derived from the Italian words "caccia" meaning "hunt" and "uppolo" meaning "little hill" or "small elevation." This suggests that the name may have initially referred to a person who lived or worked in a hilly area suitable for hunting.
One of the earliest recorded instances of the name Caccioppoli can be found in a document from the 15th century, which mentions a certain "Antonello Caccioppoli" from the town of Amalfi in the province of Salerno. This town, situated along the picturesque Amalfi Coast, was known for its maritime trade and prosperity during the Middle Ages and Renaissance periods.
In the 16th century, records show that a branch of the Caccioppoli family had settled in the city of Naples, where they became influential members of the local nobility. One notable figure from this era was Francesco Caccioppoli (1521-1589), a renowned jurist and legal scholar who served as a magistrate in the royal court of Naples.
During the 17th and 18th centuries, several members of the Caccioppoli family made significant contributions to the fields of science and academia. Notably, Gian Battista Caccioppoli (1677-1751) was a distinguished mathematician and astronomer who held the chair of mathematics at the University of Naples.
Another prominent individual bearing the surname Caccioppoli was Renato Caccioppoli (1904-1959), a renowned Italian mathematician and professor who made groundbreaking contributions to the fields of calculus of variations and partial differential equations. His work on the theory of elliptic equations, now known as the "Caccioppoli inequality," has had a lasting impact in the field of analysis.
In the realm of literature, the name Caccioppoli is associated with the writer and journalist Raffaele Caccioppoli (1894-1960), who was known for his novels and short stories depicting the everyday life and struggles of the working class in Naples.
It is worth noting that while the surname Caccioppoli is primarily concentrated in the regions of Campania and Lazio in Italy, it has also been found in other parts of the country, as well as in areas with significant Italian diaspora populations.

When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.

Keep in mind that these are self-reported numbers.
