How many people have lived in 3 centuries?

Very few individuals have lived in three centuries. The most notable examples are those who were born in the 19th century, lived through the 20th, and survived into the 21st century. One of the most famous cases is Jeanne Calment, who lived from 1875 to 1997, reaching 122 years of age. Due to the typical lifespan, only a small number of people have achieved this feat.
