American director (1928–2020) who worked on The Next Generation, Deep Space Nine and Voyager, directing Relics, Ship in a Bottle and both parts of Descent among many others.
Alexander Singer was an American film and television director with a career reaching back to the 1960s. He came to Star Trek in the sixth season of The Next Generation, where his first episode was Relics, the story that brought James Doohan back as Scotty and recreated the bridge of the original Enterprise.
He followed it with Ship in a Bottle and with both halves of Descent, the two-parter that bridged the sixth and seventh seasons.
Singer then moved on to Deep Space Nine and above all to Voyager, for which he directed a large number of episodes during its first five seasons before retiring.
