(written from a Production point of view)
Herman Fritz Zimmerman (born 19 April 1935; age 85) was an art director and production designer who worked between 1987 and 2005 for the Star Trek franchise. Excepting Star Trek: Voyager, he has in that era worked on all other live-action productions set in the prime universe, the first season of Star Trek: The Next Generation, the entire runs of Star Trek: Deep Space Nine, and Star Trek: Enterprise, as well as six Star Trek films. Together with Rick Sternbach he designed the space station Deep Space 9, with John Eaves the USS Enterprise-B and the USS Enterprise-E. His most recognizable work though, have been his (co-)designs for nearly all of the standing sets, those of the bridge, Main Engineering (co-designed with Andrew Probert) and Ten Forward for the USS Enterprise-D in particular. As head of the Art Department, Zimmerman oversaw his own team of set designers, prop masters, set decorators and production illustrators, whereas Michael Okuda's separate Scenic Art Department was subordinated and answerable to his. Zimmerman's role on the modern prime universe Star Trek productions, was equivalent to that of his illustrious predecessor Matt Jefferies for Star Trek: The Original Series.
His tenure on the eighteen year run of the modern Star Trek franchise set in the prime universe was interrupted twice. The first time occurred at the conclusion of the first season of the Next Generation when William Shatner asked him to become the production designer on Star Trek V: The Final Frontier. Shatner had been so impressed with his work on The Next Generation as such, that he hired Zimmerman to upgrade the USS Enterprise-A interiors for the film. Therefore, the upgraded bridge from the movie, for example, resembled the bright atmosphere portrayed in The Next Generation. Decades later Zimmerman later jokingly commented after seeing the film, considered so flawed by so many, "After the show was over, I was pretty sure I would never do another!" (The Art of Star Trek, p. 249; Star Trek: 45 Years of Designing the Future) For the Next Generation Zimmerman asked colleague Richard James to step in. "I asked Richard James to sub for me and he was so good at subbing for me that I just walked away from it. I did a number of other things and then came back to do DS9 and Enterprise and another five motion pictures. So that whole experience with TNG was just kind of a kick-start to my involvement with Star Trek in a real and personal way.", Zimmerman elaborated. . Nevertheless, it was during this first, 1989-1992, hiatus that Zimmerman also worked on Star Trek VI: The Undiscovered Country.
The second hiatus from the franchise occurred in the period 1999-2001, after Deep Space Nine concluded and before Enterprise went into production, and no position was available to him on the only Star Trek live-action show in production at that time, Star Trek: Voyager, simply "because it wasn't offered to me."  Voyager's Art Department was by that time already headed by Richard James. His work on Star Trek earned him four Emmy Award nominations in the category Outstanding Art Direction for a Series, coincidently all for Deep Space Nine episodes. But his work on that series did win him the 1997 ADG Excellence in Production Design Award.
Zimmerman is the father of Deep Space Nine and Enterprise set designer Fritz Zimmerman III. Starting with the 1993 Star Trek Earth Tour and setting the template for these, Zimmerman conceptualized the look and oversaw the design of Star Trek-themed attractions, intended to immerse visitors in the Star Trek universe and which included the 1995 Star Trek: The Exhibition, as well as the 1998 Star Trek World Tour and Star Trek: The Experience in Las Vegas as part of the Special Entertainment Events crew. He has been interviewed for several Star Trek documentaries and home media special features, wrote an introduction for the 1995 reference book The Art of Star Trek, and co-authored the 1998 reference book Star Trek: Deep Space Nine Technical Manual.
During the run of Star Trek, Zimmerman was often referenced on screen, including
- Lewis Zimmerman (Deep Space Nine and Voyager)
- Herman Zimmerman (Captain) (The Next Generation, Deep Space Nine, Star Trek: First Contact)
- H. Zimmerman (Enterprise)
- H. Zimmerman (Star Trek: Generations)
- Chez Zimmerman (Deep Space Nine)
- Ermat Zimm (Deep Space Nine)
- Zimmerman provided a personal image of his father and himself to the Picard family album in Star Trek Generations, standing in as ancestors of Jean-Luc Picard
- During the pre-production of Voyager, The Doctor was named "Doc Zimmerman" after him (VOY Season 2 DVD, "Text commentary "The 37's"")
Zimmerman was a huge admirer of his predecessor, Original Series Art Director Matt Jefferies, and it was through Zimmerman's efforts that much of his influences were observed in modern prime-universe Star Trek live-action productions, which included the elevation into canon of the designation "Jefferies tube" (even though he had to leave the actual canonization to his successor James). Star Trek archivist commented about Zimmerman, "He has always idolized Matt and his work. And he has always tried to incorporate Matt's work and designs and to make sure that the theme is carried on into the new TV series and all of the features." ("Designing the Final Frontier", TOS Season 2 DVD special features)
On 27 September 2009, Herman Zimmerman, together with fellow designers John Jefferies, Joe Jennings and Scott Chambliss, were honored for their Star Trek contributions in a media event called the "Star Trek Designers Talk Trek History At Art Directors Guild Event" at the Egyptian Theater in Hollywood, and in which all designers discussed in-depth their work on the franchise. The event was moderated by another Star Trek alumnus, Daren Dochterman, with Zimmerman's set designer son, Fritz Zimmerman, in attendance.  Three years later, in 2012, Herman Zimmerman was again honored by the Art Directors Guild, when they awarded him the Lifetime Achievement Award.  Due to illness, the award was accepted on his behalf by former Star Trek colleagues Mike Okuda and Doug Drexler on 2 February 2013.
