John and Bjo     John Griffin Trimble served in the US Air Force, Air Rescue, during the Korean War. Afterwards he worked for an international cordage company, then for Gallup Poll. He met Bjo at a convention party under Forrest J Ackerman’s grand piano and found himself involved in a lot of unplanned science fiction projects. John was a mainstay in the Save Star Trek letter-writing campaign, but never got much credit in the midst of the feminist movement. Now retired, John works on the Trimble’s online company, Ancient Earth Pigments, He likes mystery and history books, cheeses, home-brewed dark beer, dark chocolate, and good company.

     Bjo Trimble began her art career as a freelance graphic artist for Los Angeles area printing companies, wrote two published Star Trek books and multiple magazine articles. She served in the US Navy during the Korean War, but was never assigned overseas. Bjo originated the Art Shows and Futuristic Fashion Show for science fiction conventions. She is a long-time dyer and scroll illuminator, and currently acts as tutorial writer and Crazy Ideas person for the family business.

They live in a 105 year old Craftsman-style California bungalow in the foothills of Southern California, sharing the little house with middle daughter, Lora, and her husband, Jason.

The latter event has moved to Costume Con, where it still thrives. They both have Inkpot Awards from San Diego Comic Con for setting up the convention’s first art shows. The Trimbles also helped set up Comic Con’s masquerade contests, with the aid of actor Walter Koenig, and Jack Kirby. They rallied fandom to name the first space shuttle the "Enterprise" to draw attention to the space effort.
