Cloning Einstein

I predict that over the next 5-10 years our society will need to address what will grow into a major controversy: should we dig up Albert Einstein (and other famous scientists, historical figures, etc.) and clone them? It's likely that we'll be able to extract sufficient DNA from Einstein's corpse to create a clone of him who could grow from infancy into a normal adult. Presumably Einstein's heirs could veto such an effort (if they wanted to), but what about cloning George Washington. Who has a legitimate claim on his DNA now, hundreds of years after his death?

It may sound silly to us in 2008, but we'll be addressing this issue within our lifetimes.
