You were at 0 and I reflexively downvoted you to -1, but now I regret it - I voted a little quicker than thinking.
Upon reflection, I think this is actually an interesting point and would you care to elaborate? I love reading letters from important scientists and statesmen of old, but maybe there is some merit in respecting people's privacy even after they pass on. I'll think on this some, if you have any examples or further thought on the matter I'd be quite interested in hearing it.
