<P> Created by Bill Finger, but credited to Bob Kane, Gordon debuted in the first panel of Detective Comics #27 (May 1939), in which he is referred to simply as Commissioner Gordon . The character's name was taken from the earlier pulp character commissioner James W. "Wildcat" Gordon, also known as "The Whisperer", created in 1936 by Henry Ralston, John Nanovic, and Lawrence Donovan for Street & Smith . </P> <P> Gordon had served in the United States Marine Corps prior to becoming a police officer . This gave him a set of skills that would serve useful in the future . In most versions of the Batman mythos, Jim Gordon is at one point or another depicted as commissioner of the Gotham City Police Department . Gordon frequently contacts Batman for help in solving various crimes, particularly those committed by supervillains . Generally it is Gordon who uses the Batsignal to summon Batman, and it has become a running joke of sorts that the Dark Knight will often disappear in the middle of the discussion when Gordon's back is turned . Gordon is usually depicted with silver or red hair, eyeglasses, and a mustache . In most incarnations, he is seen wearing a trenchcoat, necktie, and on occasion, a fedora hat . He is also sometimes pictured with a cane, although it is not revealed why he uses it . Because DC Comics retconned its characters' history in the 1985 miniseries Crisis on Infinite Earths, and because of different interpretations in television and film, the details of Gordon's history vary from story to story . </P> <P> He has been married twice; first to Barbara Eileen Gordon (née Barbara Eileen Kean) and then to Sarah Essen - Gordon . </P> <P> In the original pre-Crisis version of his history, Gordon is a police detective who initially resents the mysterious vigilante's interference in police business . He first appears in Detective Comics #27, in the very first Batman story, in which they both investigate the murder of a chemical industrialist . Although Batman fights on the side of justice, his methods and phenomenal track record for stopping crimes and capturing criminals embarrasses the police by comparison . Eventually, Batman meets up with Gordon and persuades the detective that they need each other's help . Batman is deputized and works with Gordon as an agent of the law . </P>
