Robert Redford, the Oscar-winning actor, director and founder of the Sundance Institute who helped shape independent American cinema and championed conservation causes, died on September 16. He was 89.

Redford’s career spanned more than six decades and encompassed acting, directing, producing and arts philanthropy. He won two Academy Awards — one as director of Ordinary People (1980), which earned Best Picture and Best Director — and he used his influence and resources to create the Sundance Institute in 1981 and later to expand the U.S. Film and Video Festival into the now internationally recognized Sundance Film Festival, which he took over in 1985.

Born in 1936 in Santa Monica, California, Redford contracted polio as a child and later credited an early trip to Yosemite National Park with shaping his lifelong commitment to the natural world. He studied art at the University of Colorado at Boulder and spent a formative year in Europe in his late teens before turning to acting in the late 1950s. His breakthrough came on stage in Neil Simon’s Barefoot in the Park (1963), and he later reprised the role in the 1967 film opposite Jane Fonda.

As an actor, Redford chose roles that often explored American character and politics. He starred in genre-defining films including Butch Cassidy and the Sundance Kid (1969), The Sting (1973), All the President’s Men (1976), and The Way We Were (1973). In All the President’s Men he portrayed reporter Bob Woodward in a dramatization of the Watergate investigation. Later film work included A River Runs Through It (1992), which he directed, and Quiz Show (1994), which examined the 1950s television quiz scandal. In 2013 he delivered a largely wordless, critically praised late-career performance in All Is Lost.

Redford’s directorial debut, Ordinary People, won four Academy Awards, and his films as a director frequently drew attention for their literary and historical sources. His work behind the camera included adaptations of Norman Maclean’s A River Runs Through It and a return to political themes in Quiz Show. As a producer and mentor, he fostered new filmmakers through the Sundance Institute, helping to build an outlet for independent storytelling that significantly altered the U.S. film landscape.

Beyond filmmaking, Redford was known for his environmental advocacy and public statements urging preservation and civic responsibility. In a 2018 interview he said, “I think you have to maintain hope, because that’s the only life raft you’ve got,” and spoke about the necessity of resisting destruction of wild places and civic values.

Colleagues and critics have long noted Redford’s ability to communicate emotion with subtle expression, a quality that informed both his romantic leads and more politically inflected roles. His performances combined a quiet magnetism with restraint, and he regularly selected projects that engaged with questions of integrity, corruption and the possibility of redemption.

Redford’s establishment of the Sundance Institute and his stewardship of the Sundance Film Festival created a lasting institutional legacy. The festival became a vital launching pad for independent filmmakers and a key forum for work outside the studio system. Over decades Sundance nurtured a wide range of auteurs and cultivated films that might otherwise have struggled to find an audience.

He is survived by family members, colleagues and the community of filmmakers whose careers the Sundance Institute helped to launch. Redford’s work, both on screen and off, made a sustained imprint on American culture: as an actor who could convey interior life with a look, as a director and producer who received top industry honors, and as a public figure who advocated for conservation and independent storytelling.

Redford’s death marks the close of a career that intersected with major cultural and political moments of the late 20th and early 21st centuries. Throughout, he remained publicly engaged with issues that extended beyond entertainment — from environmental preservation to the civic duties of artists and citizens — leaving a complex legacy in American film and public life.
