13 side-by-side portraits of people over 100 with their younger selves

Centenarians — people 100 years or older — are a rarity. Their lives are often scrutinized as holding the key to aging.

Czech photographer Jan Langer's portrait series "Faces of Century" shows them in a different light: as human beings aged by years of experience, but at their deepest level, unchanged by the passing of time.

In the series, Langer juxtaposes his portraits with another portrait of the subject from decades earlier. He recreates the original pose and lighting as closely as he can — he wants us to see them not just as they are now, but how they have and haven't changed over time. That is the key to the series.

These are the rare faces of people who have lived through two world wars, a cavalcade of regimes, and the rush of advancements in modern life. These photos, and the stories of the lives lived by the people in them, show not only the beauty of aging, but how even as we age, we still remain essentially ourselves.

The photographer Langer was initially inspired to document the lives of elderly people because of what he saw as the media's lack of coverage of them. He decided to focus on people over the age of 100 — a very rare demographic indeed. The 2010 U.S. Census reported only 53,364 centenarians, which is only 0.19% of the population of people 70 years or older.

“One should live every single moment according to their best knowledge and conscience because one day we will see clearly what has a real value," Langer says of what he learned from his subjects while photographing them.

The series was originally part of a story that Langer did for the Czech news outlet aktuálně.cz. You can see more photos from the portrait sessions by following the link.
