A native Oklahoman, he began considering news and communications as a career in high school after being inspired by a teacher in his journalism class. He majored in Theatre at college with a journalism minor, and began writing about Star Trek because “all the Will Rogers and Sooners football books had been written.” He also cites Stephen Edward Poe’s classic The Making of Star Trek and Bjo Trimble’s Star Trek Concordance as seminal influences in entertainment and genre writing.
In 1992, Nemecek was the author of the classic Star Trek: The Next Generation Companion. He later updated this in May 1995 and in 2003. His text commentary also appeared in the CD version.
In December 1994, after moving to Los Angeles, Nemecek and his wife Janet pitched and sold a story, “Reflections,” for the yet-to-air series Star Trek: Voyager. It was shelved for six years before being updated and written as “Prophecy”, an episode for Voyager’s last season in 2001.
His earlier work with the franchise’s fictional/factual astrography came full-circle with the late 2013 publication of Star Trek: Stellar Cartography, an officially licensed book and 10-map poster set he authored and oversaw for becker & mayer and 47 North/Amazon. That project in turn updated and expanded 2002’s Star Trek: Star Charts – a reunion of sorts with onetime Star Trek Maps colleague Mandel, where he had contributed the chapter openers and other research.
In 1996 Nemecek co-wrote The Making of Star Trek: First Contact, published by Titan Books in the UK from material he, Ian Spelling, and Lou Anders wrote for Titan’s magazine specials on the film. He also authored the original 1998 museum artifact placards and the 2002 timeline update in the museum area of Star Trek: The Experience, and was a consultant there as well as on such projects as the Star Trek: Federation Science European tour and the Star Trek World Tour guidebooks and image references.
From 1998 until 2005, after publication of Star Trek: The Next Generation Companion, Nemecek served as managing editor of Star Trek: Communicator, overseeing the planning, writers, content and look of the licensed magazine of the Official Star Trek Fan Club. He has been a regular columnist in Star Trek Magazine since 1998, and contributed dozens of articles to Star Trek Fact Files, for which he worked all six years as Los Angeles photo editor and consultant. The topics researched and obscure references and sources tracked fuelled the work of the UK-based Fact Files, later seen in the US in Star Trek: The Magazine.
He was also the sole Star Trek-affiliated contributor to Star Trek: Best Episode Collection, a Fact Files/DVD partwork project for Japan, and continues his two columns for Star Trek Magazine.
Since 1986, Nemecek has conducted over five hundred archival interviews of Star Trek writers, designers, crew, and actors, most of them multiple or annual updates over the years and unpublished. Segments are now being produced under his own brand as Trekland: On Speaker. He has appeared as a documentary guest on titles such as Trek Nation and The Captains of The Final Frontier and numerous instalments of the Next Generation and Enterprise Blu-ray collection documentaries.
He currently serves as outreach spokesman for the global, non-profit Enterprise in Space project, aiming to launch 100+ student experiments and aerospace demonstrators in 2019 on a winning contest-designed orbiter craft honouring heroically inspiring sci-fi and space history, and return.
For many years, Nemecek was a contributor and producer on the official Star Trek website. In 1996, he was it’s first-ever chat guest, its managing editor one day a week, and from 1996-99 wrote much of its early database as a consultant. In December 2007, however, on his latter-day stint with the site, he and the entire StarTrek.com production team were laid off by CBS Interactive, the result of restructuring at the company.
