Louise Lasser, an actress known for her distinctive presence in 1970s comedy and her collaborations with filmmaker Woody Allen, died on July 6, 2026, at the age of 87. Her death was reported without a disclosed cause.

Born in New York City on April 11, 1939, Lasser grew up as the only child of Sol Lasser, an accountant turned successful author of tax guides, and Paula Cohen, an interior designer. She attended the private Fieldston School before enrolling at Brandeis University, where she studied political science but did not complete her degree. Lasser faced ongoing struggles with mental health throughout her life, which influenced both her personal and professional journey.

Lasser’s early career began with improvisational theatre in Greenwich Village and acting classes under Sanford Meisner. She appeared on Broadway in 1962 as an understudy to Barbra Streisand in the musical *I Can Get It for You Wholesale*. Her breakthrough came through her connection with Woody Allen, whom she met in 1958. The couple married in 1966, and Lasser became a key figure in Allen’s early films, including *Take the Money and Run* (1970) and *Bananas* (1971), where her performance aligned with Allen’s distinctive comedic style. Their marriage ended after four years, but they remained on amicable terms.

Lasser’s most prominent role was in the satirical soap opera *Mary Hartman, Mary Hartman*, which aired from January 1976 to July 1977. In the series, she played Mary Hartman, a neurotic housewife navigating the absurdities of American suburban life. The show, created during a time of national upheaval following the Vietnam War and Watergate scandals, blended dark humor with social commentary and was noted for its surreal and ironic tone, which resonated with a broad audience. Lasser’s portrayal earned her widespread recognition and appeared on the covers of major magazines, but the intense filming schedule took a toll on her well-being. During this period, she was arrested on a cocaine possession charge and made a memorable appearance on *Saturday Night Live* depicting her own emotional struggles.

Following *Mary Hartman, Mary Hartman*, Lasser continued acting sporadically in television series such as *Taxi* and *St. Elsewhere*, and had a small role in Allen’s *Stardust Memories* (1980). She later dedicated herself to teaching acting through her studio on Manhattan’s Upper East Side and appeared in occasional independent films, including the critically acclaimed *Happiness* (1998).

Lasser is survived by her longtime partner, film producer Michael Citriniti. Reflecting on her career, Woody Allen remarked on the challenges she faced and the unrealized potential of her stardom, emphasizing her unique talent and enduring influence on comedy.
