Pato Guzman Patricio " Pato " Guzman , generally credited as " Pato Guzman " , was " Star Trek " s very first art director , when he was assigned by his employer Desilu Studios to " Star Trek " s 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 successor on the regular run of , Matt Jefferies , went through something similar , but unlike Guzman , was brought to heel by the union . As " Star Trek " s 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 .
