The question of how to live a long life is not a new one — and, as TIME explores in the new issue, the answer is constantly evolving.

While the science wasn't as clear as it is today, there was no shortage of role models. A four-page photo essay shot by Alfred Eisenstaedt featured some of the nation's most notable elderly men; nine of them are featured here, with the original captions, including their ages at the time.
