Mamie Gummer Height, Weight, Age, Body Measurements, Biography & Wiki
Mamie Gummer made her film debut at 20 months old, cast alongside her mother in Heartburn (1986) — decades before she’d build an acting career entirely her own. Being the eldest daughter of Meryl Streep, widely regarded as one of the greatest actresses in film history, could have defined her career by comparison alone. Instead, Gummer built a steady, respected résumé across television, film, and stage that stands on its own merits.
Born in New York City and raised largely in rural Connecticut, Mamie Gummer trained at Northwestern University before working her way through Off-Broadway theater into television roles that made her a familiar face, all while keeping her personal life notably more private than her famous mother’s.
