When Benjamin Franklin was 22, he drafted an epitaph for himself which clearly shows that he believed in reincarnation:

In 2002, PBS broadcast a special about Franklin which included an actor, playing Franklin himself, introducing the series. In it, the actor says:

"I've had a very happy life. So much so, that I'd have no objection to living it all over again! Well, perhaps I'd correct a few errors I made the first time 'round. But since repetition is impossible, the next best thing is to remember that life. And to relate it to you."

The sentiment expressed in the introduction is very close to the epitaph--it even looks to me as if the actor playing Franklin is paraphrasing the epitaph, but turning its meaning around backwards so as to make it appear that Franklin actually disbelieved in reincarnation. This is just one of the ways that society continues to marginalize this concept. Franklin is praised to the skies in the introduction to this documentary, as a statesman, inventor, writer, and signer of the Declaration. But his belief in reincarnation is not only conveniently omitted; it is actually reversed. Had they let the actor speak Franklin's actual words, PBS's entire audience would have had to come to grips with the fact that such an influential, intelligent and thoughtful person accepted a concept which they believe is nonsense.

By the way, note that in the epitaph, Franklin mentions the "Author". That means that he believed in both God and reincarnation at the same time, while the actor mentions neither.
