Harriet Koskoff of San Francisco, formerly of Plainville, died peacefully at her home in the Castro neighborhood on Dec. 22 at age 82. Harriet was born to the late Attorney Milton M. Koskoff and Gertrude Farber Koskoff, who in the 1950s was a three-term state representative. Harriet grew up in Plainville, attended Plainville High School, and after her junior year entered Carnegie Tech (now Carnegie-Mellon University) in Pittsburgh. Despite its name, Carnegie Tech had a renowned theater department and Harriet studied playwriting there. She considered going to Yale for graduate studies at Yale Drama School, but instead, in 1958, she married Attorney William Ziering of New Britain. The Zierings relocated to San Francisco in 1960, where they both lived out their lives. Though the marriage terminated in divorce in 1994, they remained loving friends and each provided strong emotional and sometimes financial support for the other. They had one son, Benjamin Ziering of Anaheim, Calif., who survives them.
Harriet was the creator/producer of three well-regarded documentary films: Patently Offensive: Porn under Seige (1991); Despair (1995), and Culture of Emotions (2005).
William Ziering died Dec. 10, 2018, and the next day Harriet entered a Bay Area hospital after exhibiting cardiac symptoms. She was discharged to home after several days and was found slumped over her desk a few days later by her dear friend and transcendental meditation guru, Paul Brown, with whom she was in near-daily contact. Besides her son Benjamin, she leaves her brother and sister-in-law, David and Charlotte Koskoff of Plainville, and a vast circle of creative, interesting and devoted friends.
