Peter Ledger
25 October 1945 to 18 November 1994
Peter was an artist. He was a painter, designer, and creator of worlds. And without him, the Babylon 5 we all know and love would not exist. You see, while JMS was shopping the series around to the studios, and continually being turned down, he turned to Peter for help. JMS commissioned Peter to create the Babylon 5 logo, as well as conceptual artwork showing the station itself and interiors, including the character designs for the pilot "The Gathering." We all owe a great debt of gratitude to him.

You can see small versions of his conceptual work here. In addition, his wife, Christy Marx, who wrote the first season episode "Grail" has a memorial to him here.
