If you lived in Tulsa through the seventies and eighties, you either loved or hated Betsy Horowitz. Today, you’re probably grateful for her. When city planners were trying to put in a new highway system, it was Horowitz’s brazen and vocal opposition that ultimately killed the project. Today, she’s largely recognized as a visionary who helped preserve Tulsa’s architectural history.

In this episode, we hear Andrew Horowitz talk about his mother’s political aspirations. What emerges is a portrait of a larger-than-life Tulsan, one whose reach can still be felt–and seen–after her passing.
