José Guillermo "Memo" Gidley is a Mexican-American racing driver, of German and Canadian ancestry, born in La Paz, Baja California Sur, Mexico in 1973. He holds dual citizenship - American and Mexican.
In his early years, he sold his apartment to fund his career and spent 4 months homeless living in his car. He worked at the Jim Russell racing school as a mechanic to fund his career for some time, eventually getting a chance in Champ Car with Derrick Walker in 1999, although this was as a short-term replacement. He did the same task for Gerry Forsythe a year later, and Chip Ganassi in 2001, twice coming close to race victories. He nearly retained his drive for 2002 - Chip later suggested that they keep Bruno Junqueira over him as the Brazilian was under contract.
He has raced assorted sports cars since, although he made 2 Champ Car starts for Rocketsports in 2004, and briefly ran in the rival IRL series. Since 2005 he has competed full time in the Grand-Am Rolex Sports Car Series, co-driving with Michael McDowell to a victory in the Mexico City season finale. In 2006 he raced in the Team Playboy cars and in 2007 he partnered Max Angelelli in the SunTrust Racing team. In 2010 Gidley co-drove Team CytoSport's Porsche RS Spyder with Germany's Klaus Graf and Sascha Maassen to second in class (and overall) at Laguna Seca, but he reportedly hasn't given up on a return to major open wheel racing.
