Proving Ground

“Everyone told Kathy Kleiman that the women she sought did not exist. Thankfully, she didn’t believe them. In Proving Ground, Kleiman pursues her subjects with the instincts of an investigative journalist, uncovering the stories of six groundbreaking women who battled sexism, complex trajectory equations, and blown vacuum tubes in order to program the world’s first digital computer. With unforgettable, detailed prose, Kleiman blends the history of early computing with the lives of the women who made modern programming possible. Proving Ground is a book so deeply inspiring that it has the power to completely alter how we see the technology field and the role of women within it.”

“With this book, Kathy Kleiman restores the ENIAC 6 to their rightful, lauded place in the history of computing. The bond she developed with these women through her years of research and interviews is evident, as each of them come vibrantly and vividly alive in her writing. Their story will serve as inspiration for generations of women in STEM.”

“Kleiman has a novelist’s gift for crafting a page-turning narrative, and the one on offer is both revelatory and inspiring. Fans of Dava Sobel’s The Glass Universe and Margot Lee Shetterly’s Hidden Figures are in for a treat.”

“Kathy Kleiman's courageous pursuit across decades discovering and sharing the story of the extraordinary contribution of these first programmers and founding inventors gives us a gift that can change the future - empowering a more welcoming technical innovation culture for all.”

"An important and inspiring little-known narrative in modern computing history."

"Kleiman excels at capturing the pressures of working in technology during a highly stressful period in history, particularly when the results of technological trials directly impacted war efforts. . . [T]he inclusion of direct interviews with the women and the clear passion for their stories make Proving Ground a needed and welcome addition to the shelves of computer history."
