Ada Lovelace wrote the world's first program for an information processing machine in 1843. What contributions do women continue to make in the digital world today? This volume examines Ada Lovelace (1815-1852) as a pioneer of programming, as well as her stylization as an icon. It reflects on the significance of 'computing women' in the post-war era of emerging computer technology. It discusses the role of the 'subtle differences' between genders in science and technology and features important female researchers in contemporary computer science (robotics, distributed intelligence, big data).
