(written from a Production point of view)
Barbara Jean Affonso (born 5 December 1947; age 67) was a studio model maker who has been in the employ of Industrial Light & Magic (ILM). Though employed at ILM since 1983, she has worked as model maker on two Star Trek productions only.
Affonso's first Star Trek contribution was for the Star Trek: The Next Generation pilot episode "Encounter at Farpoint" in 1987, though she went uncredited for it. For that production she was one of the staffers who created the Old Bandi City maquette. (Cinefex, issue 37, p. 12) She was however, fully credited as chief model maker for her contributions for Star Trek: First Contact in 1996. On the latter production she has worked amongst others on the Borg cube model, as well as on the Borg sphere model.

Other credits in the model department include Steven Spielberg's fantasy adventure Hook (1991), the fantasy adventure The Mummy (1999), and the science fiction sequel Star Wars: Episode II - Attack of the Clones (2002).
