This issue maps out some of the ways that bodies have been measured and identified based on biometrics ever since the rise of media technologies, from nineteenth century anthropometry to modern day computational science. From case studies and interventions detailing the history and politics of biometrics, to creative and critical applications and visualizations of the biometric body, the authors and artists included here work across diverse theoretical approaches and disciplinary traditions to engage the machine-readable body. The contributions are organized around five conversations—History of Measurement; Politics and Governance; Aesthetics; Narratives and Experiences; and Design—that reflect the reach of biometrics today. One the one hand, they consider the quantified and objectified body as it becomes part of systems of identification and recognition, such as in contexts of security or surveillance.
