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".
Gollum
In the first edition of "The Hobbit" Tolkien made no reference to Gollum's size, leading several illustrators to portray him as being very large. Tolkien realized the omission, and clarified in later editions that he was of average Hobbit size. "The Lord of the Rings" characterizes him as slightly larger than Samwise Gamgee.
