A new theatrical production that premiered last week in Chicago revisits the story behind the invention of the birth control pill, offering a fresh perspective on the historical narrative. Adapted from Jonathan Eig’s 2014 book “The Birth of the Pill,” the play, written by Jessica Huang, not only dramatizes the scientific breakthrough but also critically examines aspects of the history that Eig’s original work left underexplored.

Eig, an author known for his detailed biographies, appears as a character in the play, which interweaves events from 1950 with scenes set in 2026. The production spotlights a fictional Puerto Rican woman named Ramona Delgado, who confronts Eig’s onstage persona to challenge the omissions she perceives in the chronicling of the pill’s development. Delgado represents the women in Puerto Rico who participated in early clinical trials of the contraceptive, a group whose experiences have often been marginalized or overlooked in mainstream accounts.

Throughout the 1950s, the birth control pill emerged as a revolutionary innovation amid prevailing legal restrictions and cultural resistance. Eig’s book focused largely on the key figures responsible for its creation and dissemination—Margaret Sanger, the activist; Katharine Dexter McCormick, the philanthropist; Gregory Pincus, the scientist; and John Rock, the gynecologist overseeing trials. Yet, as Eig acknowledges, the historical record has tended to center on these prominent figures, often at the expense of the thousands of low-income women, particularly in Puerto Rico, who endured severe side effects during the experimental phases without full disclosure that they were subjects in clinical research.

In reflecting on the play, Eig expressed mixed feelings. While surprised to see his work critiqued onstage, he welcomed the opportunity to engage with the complex and sometimes uncomfortable facets of history. He noted that the passage of time often reveals gaps and silences in the narratives historians tell, especially those concerning the human costs behind scientific progress. Eig also recognized that many emotional and experiential elements do not easily translate into traditional historical writing, making theater an effective medium to bring these stories to life.

The play, staged at Chicago’s Timeline Theater with Maria Victoria Martinez portraying Ramona Delgado, has been praised for its blending of humor and historical grounding, alongside its candid confrontation of difficult questions about ethics, representation, and memory. Eig described the production as a haunting call to remember the full scope of history—not only its celebrated figures and triumphs but also the suffering and sacrifices that underpinned them.

This theatrical reinterpretation underscores an ongoing dialogue about how history is recorded and recalled, encouraging audiences to reconsider whose stories are told and how. It serves as a reminder that reexamining the past is essential for understanding not only the origins of breakthroughs like the birth control pill but also the broader social implications that persist to this day.
