Sam Gamgee

Samwise Gamgee, a character from J. R. R. Tolkien's fantasy world Middle-earth, is Frodo Baggins' servant who proves to be the most loyal of the Fellowship of the Ring. A gardener by trade, Sam is a simple Hobbit of plain speech, who loves Elves and knows a bit about rope making. He lives with his father, known as The Gaffer, on Bagshot Row in the Shire, close to Bag End where Frodo lives.

As "punishment" for eavesdropping on Gandalf's conversation with Frodo regarding the dangers of the One Ring, Sam is made Frodo's first companion on his journey to Rivendell in the beginning of The Lord of the Rings. Sam saves Frodo's life more than once during the quest to destroy the Ring, and he accompanies him to the bitter end.

After Shelob attacks and seemingly kills Frodo, Sam takes the Ring intending to complete the quest. Because he holds the Ring for a couple days, he is considered one of the Ring Bearers. Sam discovers that Frodo is alive in Cirith Ungol and rescues him.

By many people's interpretation, Sam Gamgee was the "true hero" of Tolkien's story: only he is of strong enough will to renounce the Ring of his own free will.

In the 1981 BBC radio serial of The Lord of the Rings, Sam is played by William Nighy[?]. In the movies The Lord of the Rings: The Fellowship of the Ring (2001) and The Lord of the Rings: The Two Towers (2002), Sam is played by Sean Astin. It is not clear whether Astin had heard Nighy's radio performance, but both actors bring very similar characterisations to the role.
