(written from a Production point of view)
Garfield Reeves-Stevens (born 1953; age ~68), together with his wife Judith Reeves-Stevens, is one of Star Trek's best-selling original book writers. Together, the Reeves-Stevens couple wrote or co-wrote five episodes of Star Trek: Enterprise's fourth season. Being Star Trek: The Original Series fans, the couple had already written several fully licensed reference books on the subject of Star Trek previously, prior to becoming officially involved with the live-action franchise.
He, along with his wife, officially joined the production staff of an actual Star Trek production, Enterprise's fourth season, at the insistence of producers Manny Coto and Michael Sussman, who desperately needed writers imbued with a deep sense of original Star Trek lore in order to repair the perceived shortcomings original producers Rick Berman and Brannon Braga had left. By the time the series concluded its third season, it arguably had become the most controversial of the television series, subject to inspired and vehement criticism of fans – and, as it turned out after-the-fact, by production staffers as well – for its perceived violations in established continuity. With both producers held responsible for the quick loss of viewer-ship, Paramount and UPN indicated its cancellation and the apparent end of Berman's tenure as the overseer of Star Trek productions with the approach of the end of the third season. Though remaining credited, Berman and Braga were indeed essentially relegated to the role of figurehead by the franchise at the end of the third season, and their places were de facto filled for the last season by Coto and Sussman, under whose tenure much of the perceived continuity violations was redressed, aided by writers such as Judith and her husband, who, like them, had an equally thorough understanding of Star Trek lore. While the writer's couple contributed to a season that, as a whole, was generally well received, it did not save the series, as its cancellation had already been decided upon.
In appreciation, aside from the fact that it had gained him a shared official credit as "Co-Producer" for the episodes "Babel One" – "These Are the Voyages...", he also was featured alongside his wife in the last episode "These Are the Voyages..." as "Commander Brad Yacobian" (named after fellow Enterprise producer Brad Yacobian).
In 2001 he was, also with his wife, interviewed for the special feature Phase II: the Lost Enterprise on the Star Trek: The Motion Picture (The Director's Edition) DVD. In 2009 Reeves-Stevens was interviewed for the special feature "Star Trek: The Three Picture Saga" on the DVD box release of Star Trek: Original Motion Picture Collection alongside his wife, Harve Bennett, Peter Krikes, Steve Meerson, Nicholas Meyer, and Ralph Winter.
In 2007, Garfield and his wife co-created a planned zombie series entitled Alive, which would've starred John Billingsley and Gary Graham. They were to serve as showrunners of the series, which was set to debut in mid-to-late 2008. The series was never made.  A series, conceived by the couple, that did make it onto the small screen was the 2012 spin-off series of the British sci-fi show Primeval, Primeval: New World, which, however, was canceled after one season.
