M. Prince

From Memory Alpha, the free Star Trek reference

M. Prince was a space officer in the year 2370, the captain of the starship CGM Gh'aster.

Under his command, the vessel visited Jura'assic IV, and was due to arrive at Deep Space 9 on stardate 47551.8, according to an arrival roster recorded in that station's library computer. (DS9: "Whispers")

Captain Prince's 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, so it seems this could be a reference to nerdy character Martin Prince from The Simpsons.
