Bester is a surname, and may refer to:
Alfred Bester is a Babylon 5 character played by Walter Koenig. He is a senior Psi Cop and a recurring antagonist in the series. J. Michael Straczynski named the character after the science fiction writer Alfred Bester, since telepathy is a recurring theme in his work (most notably The Demolished Man, which partly may have inspired the Psi corps and the "death of personality" legal punishment in the Babylon 5 universe).
The birth, life and death of Alfred Bester is chronicled in the Psi Corps Trilogy by Gregory Keyes, which reveals that the infant Stephen Kevin Dexter had been renamed by his grandfather, Kevin Vacit, in order to conceal his parentage. His chosen assumed name refers to the science fiction author, Alfred Bester.
