Gollum
Gollum is a fictional character from J. R. R. Tolkien's legendarium. He was introduced in the 1937 fantasy novel "The Hobbit", and became an important character in its sequel, "The Lord of the Rings". Gollum was a Stoor Hobbit of the River-folk, who lived near the Gladden Fields. Originally known as Sméagol, he was corrupted by the One Ring and later named Gollum after his habit of making "a horrible swallowing noise in his throat".

Due to the influence of the One Ring, Gollum's life was extended far beyond that of other members of his clan. An average Hobbit lifespan is over 100 years, but a span of 556 years separates Gollum's finding of the Ring in and its destruction in T.A. 3019, by which time he would have been approaching an age of 600 years.
