American actor (1951–2017) who played Dulmur, one of the two Department of Temporal Investigations agents, in the Deep Space Nine episode Trials and Tribble-ations.
Jack Blessing was an American actor with many television credits, including recurring roles in Moonlighting and George Lopez.
In the fifth-season Deep Space Nine episode Trials and Tribble-ations he plays Dulmur, one half of a pair of humourless investigators from the Federation's Department of Temporal Investigations who come to the station to question Sisko.
Sisko's account of the Defiant's trip back to the time of the original Enterprise and Space Station K-7 is told to Dulmur and his partner Lucsly. The agents' names are anagrams of Mulder and Scully from The X-Files.
