(written from a Production point of view)
Terry J. Erdmann (born 8 August 1943; age 72) is an author and publicist. A graduate of UCLA, Erdmann resides in Southern California with his wife, Trek editor, licensing liaison and fellow author Paula M. Block.
Having worked as a publicist for ten years - helping to create the marketing campaigns on films including Star Trek V: The Final Frontier, Cocoon, Aliens, Willow, and Stargate - Erdmann was approached by Pocket Books editor Kevin Ryan in 1993 to create a companion book for Star Trek: Deep Space Nine. He spent the next seven years documenting the creation production - the resulting work being published as the Star Trek: Deep Space Nine Companion, which he co-wrote with Block. A supplementary work, The Magic of Tribbles: The Making of Trials and Tribble-ations was also produced, written by Erdmann, Block and Gary Hutzel.
Amongst Erdmann's other Trek works are Star Trek: Action! and The Tribble Handbook. He co-wrote The Secrets of Star Trek: Insurrection with Block, and was a contributor to Star Trek: Where No One Has Gone Before. He and Block also wrote the introduction of the Prophecy and Change anthology and Erdmann himself wrote the introduction of Duty, Honor, Redemption.
In his non-Trek works, Erdmann has written companion books to series such as Ira Steven Behr and Rene Echevarria's The 4400, and Monk. He appears, along with Denise Okuda, in the special edition DVD release of The Adventures of Buckaroo Banzai Across the Eighth Dimension.
