Nicole Hollander, a biting cartoon artist, whose comic strip “Sylvia,” about a big-haired, cigarette-smoking, cat-loving, hyper-opinionated feminist, made her a singular voice on the funny pages for more than 30 years, died on April 23 in Chicago. She was 86.

Ms. Hollander made Sylvia a tart-tongued, witty, loquacious single mother who held court — sometimes from her bathtub — on sex and relationships, politics, health care reform, the environment, and other hot-button issues. The strip was syndicated in about 80 newspapers.
