Pato Guzman
Patricio "Pato" Guzman , generally credited as "Pato Guzman", was Star Treks very first art director, when he was assigned by his employer Desilu Studios to Star Treks very first production, the pilot , in .

For "The Cage", Guzman was officially credited as "production designer", then a far more coveted title, but this was effectively an illegal credit, as he had at the time only recently become an officially union designated art director. Carrying the title had to be approved by the powerful  labor union, which it had not, and would have made him the boss of his actual boss, Art Director Rolland M. Brooks, the senior staffer in Desilu's art department at the time. It is conceivable that Guzman was given the title by the studio for his personal relationship with the former Lucille Ball-Desi Arnaz couple. But since the pilot was not aired, it never had been an issue and when "The Cage" was finally released to the general public on VHS in 1986, Guzman went uncredited. His subordinate and later successor on the regular run of , Matt Jefferies, went through something similar, but unlike Guzman, was brought to heel by the union. 

As Star Treks art director, Guzman was tasked with creating the look of the futuristic setting of Star Trek from scratch, which he did in a series of color paintings. With a lot of input from Gene Roddenberry and several outside advisors, Guzman conceptualized the interior sets for "The Cage", and also did preliminary work on the 's exterior and bridge. The finalization of the designs for the latter two were subsequently largely assigned to Guzman's assistant, Matt Jefferies, a 'regular' set designer at that time. A few of Guzman's sketches were reproduced in The Art of Star Trek in .

Homesick, Guzman left the series around  to return to his native Chile for a year, before the first pilot began filming. He was replaced by Art Director Franz Bachelin, followed by Brooks himself, when Bachelin left as well after "The Cage", and ultimately by Jefferies during the production run of the regular series.
