A star of the stage and screen, Mamie Gummer was literally born with the acting gene. Her mother was Hollywood royalty Meryl Streep, one of the most acclaimed and beloved actors in the entertainment industry. Gummer began acting as a child, often taking on minor roles in feature films that starred her mother, before carving out her own career as a theater performer. She starred in numerous stage productions as a student at Northwestern University and then as a Broadway actress. Gummer took on challenging roles onscreen, from portraying a Revolutionary War-era figure in "John Adams" (HBO, 2008), to playing the assistant of the man who organized the most famous music festival in history in "Taking Woodstock" (2009). After establishing herself as a promising young actress in vehicles like the medical comedy-drama "Emily Owens, M.D." (ABC 2012-13), Gummer reunited with her mother in Jonathan Demme's comedy-drama "Ricki and the Flash" (2015).
