Discussion of the Upright Citizens Brigade Theatre has to begin with Amy Poehler. Though there were numerous members of the original Upright Citizens Brigade improv troupe in Chicago (including Adam McKay and Horatio Sanz), Poehler was one of the four members of the group to move to New York and open the first UCB location in an abandoned strip club in Chelsea, along with Matt Besser, Matt Walsh, and Ian Roberts.

Two years after making their move to New York, the four founders landed a television show with Comedy Central, also called The Upright Citizens Brigade. The show ran for three seasons. The next year Poehler landed at Saturday Night Live. Numerous film roles and Parks and Recreation followed, cementing Poehler as one of the biggest names in comedy worldwide.

Like long-time friend and collaborator, Tina Fey, Poehler's influence has transcended comedy; she's become an icon for women breaking into industries dominated by men. Time recognized this, naming her to their list of "The 100 Most Influential People in the World" in 2011.
