The definitive history of America’s greatest incubator of innovation and the birthplace of some of the 20th century’s most influential technologies “Filled with colorful characters and inspiring lessons . . . The Idea Factory explores one of the most critical issues of our time: What causes innovation?” —Walter Isaacson, The New York Times Book Review “Compelling . . . Gertner's book offers fascinating evidence for those seeking to understand how a society should best invest its research resources.” —The Wall Street Journal From its beginnings in the 1920s until its demise in the 1980s, Bell Labs-officially, the research and development wing of AT&T-was the biggest, and arguably the best, laboratory for new ideas in the world. From the transistor to the laser, from digital communications to cellular telephony, it's hard to find an aspect of modern life that hasn't been touched by Bell Labs. In The Idea Factory, Jon Gertner traces the origins of some of the twentieth century's most important inventions and delivers a riveting and heretofore untold chapter of American history. At its heart this is a story about the life and work of a small group of brilliant and eccentric men-Mervin Kelly, Bill Shockley, Claude Shannon, John Pierce, and Bill Baker-who spent their careers at Bell Labs. Today, when the drive to invent has become a mantra, Bell Labs offers us a way to enrich our understanding of the challenges and solutions to technological innovation. Here, after all, was where the foundational ideas on the management of innovation were born.

It is important to understand what came before and how to meld new products with legacy systems. Network managers need to understand the context and origins of the systems they are using. Programmers need an understanding of the reasons behind the interfaces they must satisfy and the relationship of the software they build to the whole network. And finally, sales representatives need to see the context into which their products must fit.

Race on the Line is the first book to address the convergence of race, gender, and technology in the telephone industry. Venus Green—a former Bell System employee and current labor historian—presents a hundred year history of telephone operators and their work processes, from the invention of the telephone in 1876 to the period immediately before the break-up of the American Telephone and Telegraph Company in 1984. Green shows how, as technology changed from a manual process to a computerized one, sexual and racial stereotypes enabled management to manipulate both the workers and the workplace. More than a simple story of the impact of technology, Race on the Line combines oral history, personal experience, and archival research to weave a complicated history of how skill is constructed and how its meanings change within a rapidly expanding industry. Green discusses how women faced an environment where male union leaders displayed economic as well as gender biases and where racism served as a persistent system of division. Separated into chronological sections, the study moves from the early years when the Bell company gave both male and female workers opportunities to advance; to the era of the “white lady” image of the company, when African American women were excluded from the industry and feminist working-class consciousness among white women was consequently inhibited; to the computer era, a time when black women had waged a successful struggle to integrate the telephone operating system but faced technological displacement and unrewarding work. An important study of working-class American women during the twentieth century, this book will appeal to a wide audience, particularly students and scholars with interest in women’s history, labor history, African American history, the history of technology, and business history.
