Origin
Meaning and origin of Corridori
The surname CORRIDORI has its origins in Italy, with the earliest recorded instances dating back to the 14th century. The name is believed to be derived from the Italian word "corridore," which means "runner" or "messenger." This suggests that the surname may have been given to individuals who worked as couriers or messengers, delivering important messages and documents on foot or horseback.
During the Renaissance period, the CORRIDORI name can be found in historical records from various Italian cities, particularly in the regions of Tuscany and Lombardy. In 1427, a document from the city of Florence mentions a certain Piero CORRIDORI, who was a respected merchant and member of the local guild.
The surname CORRIDORI also appears in several medieval manuscripts, including the Codice Diplomatico Longobardo, a collection of legal documents from the Lombard kingdom. One such document, dated 1286, refers to a man named Guglielmo CORRIDORI, who was involved in a land dispute.
In the 16th century, the CORRIDORI family gained prominence in the city of Milan. Giovanni Battista CORRIDORI (1497-1568) was a renowned physician and scholar who authored several influential works on medicine and natural philosophy. His son, Alessandro CORRIDORI (1532-1599), followed in his footsteps and became a respected physician and professor at the University of Pavia.
Another notable figure was Antonio Maria CORRIDORI (1668-1737), a Jesuit priest and mathematician who taught at the University of Bologna. He made significant contributions to the field of mathematics and published several treatises on geometry and calculus.
The name CORRIDORI has also been associated with various place names in Italy. For instance, the village of Corridonia, located in the Marche region, is believed to have derived its name from the surname CORRIDORI, indicating that members of this family may have been among the earliest settlers or landowners in the area.
Throughout history, the CORRIDORI surname has been spelled in various ways, including Corridore, Corridori, and Corredori, reflecting regional variations and linguistic changes over time. However, the core meaning and origin of the name have remained consistent, tracing back to the profession of messenger or runner in medieval Italy.

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.
