Classic Films

Jess Search, a producer on dozens of important documentaries and a catalyst on many more as one of the directors of Doc Society, a nonprofit organization she helped found in 2005 that supports documentary filmmakers, died on July 31 in London. She was 54.

Doc Society said in a statement that the death, in a hospital, was caused by brain cancer. Search had announced last month that she was stepping away from the organization because of her illness.

Search had been a central figure in the documentary scene in Britain and beyond for years. She was gender nonconforming (she used the pronouns “she” and “her” but preferred not to use the gendered courtesy title Ms.), and she had a special interest in promoting work by filmmakers from underrepresented populations or that dealt with out-of-the-mainstream subjects.

She was a producer or executive producer on some of those films, like Matthew Barbato’s “Alexis Arquette: She’s My Brother” (2007), about a sex reassignment surgery, and Agniia Galdanova’s “Queendom,” which was released earlier this year and is about a queer Russian performance artist.
