Walter Bishop (Fringe)
Fringe is an American science fiction television series created by J. J. Abrams, Alex Kurtzman, and Roberto Orci. It premiered on the Fox television network on September 9, 2008, and concluded on January 18, 2013, after five seasons comprising 100 episodes. An FBI agent, Olivia Dunham ; a genius but dysfunctional scientist, Walter Bishop ; and his son with a troubled past, Peter Bishop, are all members of a newly formed Fringe Division in the Federal Bureau of Investigation. Based in Boston, Massachusetts, the team uses fringe science to investigate a series of unexplained and often ghastly occurrences which are related to a parallel universe.
Marketing posters used to promote the series often featured one of the glyphs used in the show's interstitial, each being a twist on a common image. Pictured here is a leaf with an embedded Greek capital letter delta.
