Robert Yager was born and grew up in London, England. Fluent in Spanish, he lived in Mexico City for a year and then at 21 years of age, he moved to Los Angeles to study photography.

In January 1992, the year of the Rodney King LA Riots and the highest murder rate, Yager began his intimate photography with the WestSide Playboys 13 Gang. Yager explored the cultural and human side of gang members, which he hadn’t previously seen in mainstream media at that time.

Yager became a freelance editorial photographer in 1993, starting off with a Newsweek cover and he began working for the LA Weekly and the U.K.’s Observer Magazine. Soon afterwards he was working for: The New York Times Magazine, The Independent Magazine (U.K.) The Face, The Telegraph Magazine, Marie Claire, TIME, Fortune, Fader and on occasion: Rolling Stone and Esquire. He shot covers, reportage features and portraits.
