John S. Boskovich, 49; Artist Co-Wrote Film With Sandra Bernhard

John Steven Boskovich, 49, who co-wrote the movie “Without You I’m Nothing” with comedian and actress Sandra Bernhard, the star of the 1990 film, was found at his home in Los Angeles on Sunday Sept. 24 by his studio assistant, Brooke Dammkoehler.

The cause of death was being determined in an autopsy.

Boskovich first worked with Bernhard on her one-woman off-Broadway show. They later adapted the show to film. In those years, he also exhibited his art at the Rosamund Felsen Gallery, now in Santa Monica, from 1988 to 1999.

He used photography, handwritten and typeset texts and often returned to the theme of sexual politics, which he explored with edgy humor.

For several years in the 1990s he taught art at the Otis College of Art and Design in Los Angeles.

Boskovich was born Dec. 8, 1956, raised in the San Fernando Valley and graduated from USC. He earned a master’s degree in fine arts at California Institute of the Arts, where he was a student of conceptual art pioneer John Baldessari, who became a mentor.

While he was a student at CalArts, Boskovich also earned a law degree at Loyola Law School but never practiced law.
