A native of Leones, Argentina, Eduardo Risso began drawing professionally in 1981 with the magazine strips "Julio Cesar" and "El Angel." In 1986 he began an association with writer Carlos Trillo that continues to this day — their collaborations include the titles Fulù, Simon: An American Tale, J.C. Benedict, Chicanos and Borderline. After breaking into American comics in 1997, Risso first worked with writer Brian Azzarello on the 1998 Vertigo miniseries JONNY DOUBLE, which led directly to their partnership on 100 BULLETS as well as the DC graphic novel BATMAN: BROKEN CITY, FLASH POINT and currently, the Vertigo limited series SPACEMAN. Risso's work on 100 BULLETS has earned him four Eisner Awards, two Harvey Awards and the Yellow Kid Award.
