Gollum, originally known as Sméagol (or Trahald), was at first a Stoor, one of the three early Hobbit-types. The name Gollum was derived from the sound of his disgusting gurgling, choking cough. His birth can be estimated to have happened in the year TA 2430. His death date is given as March 25, 3019. His life was extended far beyond its natural limits by the effects of possessing the One Ring. At the time of his death, Sméagol was about 589 years old, a remarkable age for a creature that was once a Hobbit, but he had been deformed and twisted in both body and mind by the corruption of the Ring. His chief desire was to possess the Ring that had enslaved him, and he pursued it for many years after Bilbo Baggins found it while walking in the Misty Mountains in the book The Hobbit. In the movies, he was a deuteragonist.
