S. Sondheim
From Memory Alpha, the free Star Trek reference
S. Sondheim was a space officer in the year 2370, the captain of the starship USGS Powell.
Under his command, the vessel visited Hispaniola Minor, and was due to arrive at Deep Space 9 on stardate 47550.5, according to an arrival roster recorded in that station's library computer. (DS9: "Whispers")
His 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. He was possibly named after composer Stephen Sondheim.
