J. R. Rasmussen was an ancestor of time-travelling con man Berlinghoff Rasmussen. She encountered her descendant when he landed his stolen time-travel pod on her pool deck. The two of them then traveled to the year 1964, where they shared their first-hand knowledge of the 23rd and 24th centuries with television writer Gene Roddenberry.
Later, the two offered their research services directly to the producers of Star Trek: The Next Generation, Star Trek: Deep Space Nine, and Star Trek: Voyager. J. R. continued to do so even after Berlinghoff was killed in an auto accident.
