Berlinghoff Rasmussen

Berlinghoff Rasmussen was a male human in the 22nd century, living in New Jersey on Earth.

In the early 2150s, Rasmussen claimed to have been on Titanias III, where he met a Klingon who identified himself as being a member of the House of Duras. (DS9 novel: The Big Game)

Rasmussen was visited in his own time by a time traveller from the 26th century. Rasmussen managed to steal the historian's time-travel pod, and travel forward through time to 2368. There, he boarded the Enterprise-D and, posing as a future historian himself, stole numerous pieces of 24th century technology, which he planned to claim credit for "inventing" in the past. His plot was foiled by the Enterprise crew, and Berlinghoff was stranded in the 24th century when the pod's automatic recall was triggered. (TNG episode: "A Matter of Time")

Rasmussen spent some time in custody, but was deemed rehabilitated by 2369. That year, he participated in a high-stakes poker tournament at Quark's on Deep Space Nine. (DS9 novel: The Big Game)

Berlinghoff had the foresight to hide blueprints for the time-travel pod prior to his journey, and was able to retrieve them, thus rebuilding the pod. He then travelled back to the late 20th century, to the home of his ancestor, J. R. Rasmussen. Together, they travelled back to 1964, where they relayed information about the future to a television writer named Gene Roddenberry. Rasmussen died sometime before 1999, in an auto accident while driving to an appointment with producers at Paramount Pictures. (DS9 short story: "Research")

Writers of "ENT" originally proposed a "time loop" backstory for Rasmussen. It had him as the former roomate (at Massachusetts Institiute of Technology) of Jonathan Archer. After all the time "ripples" had taken place, this led up to his descendant's existence and the current-possibly paradoxed-timeline as we know it.
