Biography
Summer Glau's path to becoming a genre television favorite was as unconventional as the characters she would later play. Trained as a ballet dancer from childhood, a career-ending injury forced a pivot that led her to Los Angeles. Her unique physicality and expressive presence caught the eye of Joss Whedon, who cast her as the enigmatic and dangerous River Tam in the short-lived series 'Firefly.' That role, a fusion of balletic grace and lethal precision, became her signature, turning Glau into a symbol of the show's enduring legacy. She later leveraged that notoriety into a series of roles that played on her ability to seem both fragile and formidable, most notably as the relentless cyborg Cameron in 'Terminator: The Sarah Connor Chronicles.' While she has stepped back from the spotlight in recent years, her performances remain touchstones for fans who see in her work a rare and compelling artistry.
Millennials
1981–1996
The first digital natives. Grew up with the internet, came of age during 9/11 and the 2008 crash. Highly educated, deeply indebted, slower to marry and buy houses. Redefined work, identity, and what it means to be an adult.
Summer was born in 1981, placing them squarely in the Millennials. The events that shaped this generation — the internet revolution, 9/11, and the 2008 financial crisis — shaped the world they entered and the choices available to them.
