Early Life and Family

Mamie Gummer was born in New York City. She is the oldest daughter of actress Meryl Streep and sculptor Don Gummer. A sculptor is an artist who creates three-dimensional art. She grew up in Connecticut and Los Angeles with her older brother, Henry, and her younger sisters, Grace and Louisa, who are also actresses.

Acting Career

After college, she began her professional acting career on the stage. In 2005, she performed in an off-Broadway play called Mr. Marmalade. Off-Broadway theaters are smaller than Broadway theaters and often show new or experimental plays. Her performance was so good that she won a Theatre World Award.
