S. Crane was a starship captain in the 24th century. He was the commander of the FGMS Gyt'aerat.
In 2370, he was listed on the Deep Space 9 arrival roster. (DS9: "Whispers", production art)
This character was apparently named after the American author Stephen Crane, whose most famous work is The Red Badge of Courage. The name was not mentioned in dialog, it was simply listed in an okudagram graphic of an arrival roster on a viewscreen. The graphic was also populated by a number of other in-jokes.
