One of the earliest documented individuals bearing this surname was Tommaso Janni, a renowned painter and fresco artist who lived in the late 14th century. His works can still be admired in various churches and buildings across Tuscany, including the Basilica of Santa Croce in Florence.

Notably, Bartolomeo Janni (1460-1535) was a respected banker and financier, known for his involvement in the establishment of the Monte dei Paschi di Siena, one of the oldest surviving banks in the world.

In the 17th century, the Janni surname gained further recognition with the birth of Girolamo Janni (1612-1680), a Jesuit scholar and philosopher. His writings on theology and natural sciences were highly regarded during his time, and he is considered one of the most influential thinkers of the Baroque era.

Another notable figure was Antonio Janni (1740-1815), a celebrated architect and urban planner from Naples. He was responsible for the design and construction of several prominent landmarks in the city, including the Teatro di San Carlo, one of the oldest and most prestigious opera houses in Europe.

In more recent times, the Janni surname has been associated with various fields, from academia to the arts. One such individual was Ettore Janni (1892-1975), an Italian classical philologist and scholar who made significant contributions to the study of ancient Greek literature and mythology.
