Alex Prager was born in Los Angeles in 1979. She was raised by her grandmother in a small apartment in the suburb of Los Feliz. Her nomadic upbringing saw her splitting her time between Florida, California, and Switzerland without truly settling down long enough for a formal education. Prager's interest in art began in her adolescence, but it was in her early twenties that she began to focus on photography after being inspired by the work of William Eggleston.
In keeping with her independent spirit, she eschewed art school and began taking photographs on her own, teaching herself equipment and lighting through trial and error. Prager has since contributed to a number of publications including Details, i-D, Elle Japan, Tank, MOJO, and Complex. All the while, continuing to exhibit her work in various galleries worldwide.
After the release of her first book The Book Of Disquiet (2005) Prager was given her first solo show at the Robert Berman Gallery in Santa Monica, CA entitled Polyester. Her 2008 exhibition The Big Valley shown by the Michael Hoppen Gallery, London, received critical acclaim.
