Rodolfo Francisco Acuña, a pioneering American historian, educator, and revered figure often called the “father of Chicano Studies,” passed away peacefully on March 23, 2026, at the age of 93. Surrounded by his family in California, Dr. Acuña leaves behind an indelible legacy that reshaped the understanding of Mexican American history and identity in the United States.

Born on May 18, 1932, in the Boyle Heights community of Los Angeles, California, Acuña's early life was deeply rooted in the experiences of Mexican Americans. He pursued higher education with dedication, earning his bachelor's and master's degrees from Los Angeles State College (now California State University, Los Angeles) and later a Ph.D. in history from the University of Southern California in 1968.

Dr. Acuña's most profound impact came in 1969 when he founded the Chicana/o Studies department at California State University, Northridge. This groundbreaking initiative established arguably the first department of its kind in the nation, providing a vital academic home for the study of Mexican American history, culture, and social issues. He served as its first chair and remained a professor emeritus at the institution, which grew to become the largest Chicana/o Studies program in the United States.

His seminal work, "Occupied America: A History of Chicanos," first published in 1972, became a foundational text in the field. The book introduced the concept of "internal colonialism" to frame the experiences of Chicanos, challenging prevailing historical narratives and inspiring generations of students, scholars, and activists. It has been continuously revised and reprinted, serving as a core text in Chicano/a Studies courses nationwide.

Throughout his distinguished career, Dr. Acuña was a prolific author, publishing over twenty books and numerous articles, many of which received critical acclaim. He was honored with multiple Gustavus Myers Awards for Outstanding Book on Race Relations in North America for works such as "Occupied America" and "Anything But Mexican: Chicanos in Contemporary Los Angeles." His contributions were recognized by his peers when he was named a NACCS Scholar by the National Association for Chicana and Chicano Studies in 1989, the highest honor bestowed by the organization.

Beyond his academic achievements, Dr. Acuña was a tireless activist and advocate for social justice. He co-founded the Labor/Community Strategy Center in 1989, a civil rights advocacy group, and consistently spoke out on issues affecting Latino communities, including immigration and the censorship of ethnic studies. His unwavering commitment to challenging injustice earned him recognition as one of the "100 Most Influential Educators of the 20th Century" by Black Issues In Higher Education.

Dr. Acuña's dedication to education and activism extended for over six decades, mentoring thousands of students and shaping academic discourse. He received a Lifetime Achievement Award from the National Hispanic Institute in 2008 and a similar honor from the Mexican American Legal Defense and Education Fund (MALDEF) in 2010. Even while battling Parkinson's disease in his later years, he continued to write and inspire, demonstrating remarkable resilience and a steadfast commitment to his "voz" – his voice.

Rodolfo F. Acuña's legacy is one of intellectual brilliance, profound scholarship, and an unyielding commitment to justice and the power of education. His work has left an indelible mark on countless individuals and will continue to influence the study of Chicano history and identity for generations to come.
