++Tuor
Since Sauron made the short-sighted mistake of linking his power and nearly all his existence into a small thing that could be taken from him and destroyed, while Tuor may have been the only mortal to be granted the Elven kind of immortality. Plenty of people have made ill-fated "doomsday weapons" (though perhaps Sauron has the distinction of being the first), while Tuor did what no one else has, before or since. As far as we know.
