Haskell Wexler, the influential cinematographer who won Oscars for his work on 1966’s “Who’s Afraid of Virginia Woolf?” and 1976’s “Bound for Glory,” died at the age of 93. Haskell Wexler was one of the most creative and significant cinematographers in movie history. The cinematographer is primarily responsible for the lighting and framing of films, and Wexler — with his dramatic black-and-white compositions, his painterly use of color and his expert eye for dramatic angles — was one of the best.

A longtime liberal activist, Wexler photographed some of the most socially relevant and influential films of the 1960s and 1970s, including the Jane Fonda-Jon Voight anti-war classic, Coming Home, the Sidney Poitier-Rod Steiger racial drama In the Heat of the Night, The Conversation, and American Graffiti as well as One Flew Over the Cuckoo’s Nest.

In 2013’s Four Days in Chicago, he returned to the setting of Medium Cool and his hometown to document the Occupy Movement’s demonstrations against the 2012 NATO Summit.

In 2005, Wexler was the subject of a documentary, Tell Them Who You Are, directed by his son, Mark Wexler. His son Jeff works as a sound mixer. In addition to his sons, Wexler is survived by third wife Rita Taggart, an actress and cinematographer, and a daughter, Kathy.
