Biography

Jason Alexander, born Jay Scott Greenspan in Newark, New Jersey, built a formidable stage career before television immortality found him. A classically trained singer and dancer, he won a Tony Award for his performance in Jerome Robbins' Broadway. But it was his casting as the chronically scheming, perpetually unlucky George Costanza on Seinfeld that etched him into the cultural firmament. Alexander mined his own neuroses and a deep understanding of human frailty to shape George, a character of such profound and relatable failings that he became a comic archetype. Despite the role's shadow, he has consistently returned to the stage and taken on varied character work, directing for theater and television, and proving his talents extend far beyond the confines of a fictional New York apartment. His career is a masterclass in how a single, perfect performance can define an actor without limiting him.

Baby Boomers

1946–1964

The largest generation in history at the time. Shaped by postwar prosperity, the Vietnam War, the sexual revolution, and Watergate. They questioned every institution their parents built — then ran them.

Jason was born in 1959, placing them squarely in the Baby Boomers. The events that shaped this generation — postwar prosperity, civil rights, Vietnam, and the counterculture — shaped the world they entered and the choices available to them.
