Born in Múzquiz, Coahuila, Julio Galán studied architecture at the Universidad de Monterrey before dedicating himself to painting. He emerged as a significant figure in the Latin American art scene during the 1980s, gaining international attention for his expressive style that diverged from the traditional muralist movements of his home country.

His work is characterized by a recurring use of self-portraiture, often blending traditional Mexican iconography with surrealist and neo-expressionist sensibilities. He frequently utilized mixed media, incorporating collage, text, and found objects to construct complex, dreamlike narratives that interrogated the self and the complexities of gender and masculinity.

Galán's legacy continues to be examined in contemporary institutional contexts, including his inclusion in thematic group exhibitions exploring the evolution of masculinity in art. His contributions remain a vital reference point for understanding the intersection of personal identity and regional artistic movements in the late 20th century.
