Who are all the characters in The Lord of the Rings to have touched The One Ring, actually worn it on their fingers, or otherwise had it in their possession (even for a brief period of time)? Please indicate the type of contact, duration, order, and any other pertinent information.
Sauron wore it... though in the movie it is worn over a glove... but that means nothing in the grand scheme of things.
Isildur wore it. This was why he could not bring himself to destroy it.
There was never a real list of what might have happened to it After Isildur wore it as the thing was 'lost' and found in the river.
Déagol touched it, since he was a poor river thing I would admit that it was skin contact on the hand and probably why he would not give it up to Sméagol and Sméagol had to kill him for it.
Sméagol wore it and it turned him into Gollum.
Bilbo wore it as that was how he escaped Gollum, and subsequently uses it after that.
Frodo wore it, as that was how the story and movie was based.
and he was wearing it when Gollum bit it off his finger.
Gandalf touched it, more than likely skin contact as to why you see him toss the ring down and recoil from it, to place the ring in something protective to give to Bilbo.
Bombadil wore it, and the ring disappeared rather than Tom disappearing.
Samwise touched it and wore it as a necklace for sometime until Frodo was back. I believe he never wore it on his finger, though I would like to conclude he might have made a better ringbearer.
Gollum touched it again
and died with it when the ring was destroyed.
