Methuselah

According to the Bible, Methuselah was the oldest person who ever lived. He reportedly reached the age of 969 years. (See Genesis 5:27.) He is mentioned in Genesis as the son of Enoch and the father of Lamech[?]. His name has become a general synonym for any living creature of great age.

Robert Heinlein wrote a science fiction series about rejuvenation and a project called the 'Howard family' that was working to extend the human lifespan beyond a hundred and fifty years - the first volume was called Methuselah's Children.
