Age: 64
Occupation: President and CEO of Time’s Up

Michelle Obama’s former chief of staff — who was in the media glare last year for allegedly using her connections with the Cook County state’s attorney to sway the Jussie Smollett case — runs one of the most tangible outcomes of the #MeToo movement: a nonprofit that confronts gender inequity in the workplace. Under Tchen’s leadership, the group has moved beyond gestures like persuading starlets to wear black to the 2018 Golden Globes and has since provided PR and legal aid to more than 4,000 women who don’t have a slew of IMDb credits.
