Noah Gregoropoulos

Noah Gregoropoulos (1959-2022) was an American improviser and teacher who spent four decades at the center of Chicago's long-form improv scene. A New England native and Northwestern University graduate, he joined the ImprovOlympic during its formative years in the mid-1980s and became a defining figure in iO's educational lineage. He was a member of Jazz Freddy, the influential 1990s Chicago ensemble, and of the iO team Carl and the Passions, and was a regular performer in the Armando Diaz Experience shows. At Second City he directed the theater's first long-form improv show, Lois Kaz, in 1994. When Del Close died in 1999, Gregoropoulos took over Close's graduating-level class at iO.

Gregoropoulos was a New England native who graduated from Northwestern University and joined the ImprovOlympic, as it was then called, during its formative years in the mid-1980s. He became a core performer and teacher at the theater, with iO serving as his primary institutional home throughout his career.

As a performer, Gregoropoulos was known for his droll intelligence and commitment to ensemble support over individual recognition. He performed with Jazz Freddy, a groundbreaking 1990s Chicago ensemble, as well as the iO team Carl and the Passions. He was also a regular performer in the Armando Diaz Experience shows at iO, a long-form format built around a monologist whose stories inspire scenes.

At Second City he directed the theater's first long-form improv show, Lois Kaz, in 1994, an early experiment in bringing Harold-based long-form structure to a venue that had been exclusively associated with scripted revue. In 1998 he directed the Second City e.t.c. revue If The White House Is A-Rockin', Don't Come A-Knockin'.

When Del Close died in 1999, Gregoropoulos took over Close's graduating-level class at iO, the Level 5B course through which students had to pass to earn placement on Harold teams. This succession positioned him as one of the primary inheritors of Close's pedagogical tradition at the theater.

He taught improv at DePaul University's Theatre School as adjunct faculty from 2012 to 2020, extending his influence into formal university theatre training. He continued performing and teaching at iO until late in his life. Adam McKay, the writer-director of Anchorman, The Big Short, and Don't Look Up, said that no one was smarter, funnier, or loved improvisation more than Gregoropoulos.

Historical Context

Gregoropoulos joined iO during its formative period in the mid-1980s, when Del Close was developing the Harold and establishing the philosophical framework for long-form improv that would define iO's identity. His arrival at that moment placed him within the founding generation of Chicago long-form practitioners. His subsequent four decades at iO gave him a direct and continuous connection to the tradition Close had built.

His succession to Close's graduating-level class in 1999 was institutionally significant because that class served as the gatekeeper for Harold team placement at iO. Performers who could not pass that course could not advance to house team status, making the instructor of that class one of the most consequential teaching roles in Chicago long-form improv.

Jazz Freddy, the 1990s ensemble in which Gregoropoulos performed, is regarded as one of the most influential productions in Chicago improv history, credited with demonstrating that long-form could produce work of serious theatrical quality.

Legacy

Gregoropoulos's forty-year career at iO, his succession to Del Close's most advanced teaching role, and his influence on the long-form improv community through DePaul University and iO's training program place him among the central figures in the transmission of Chicago long-form pedagogy from the first to the second and third generations. His commitment to support, patience, and ensemble integrity rather than individual attention was documented by students and colleagues after his death as a defining contribution to iO's teaching culture. Adam McKay's tribute summarized the standing he had earned across multiple decades among Chicago's leading improv practitioners.
