Since World War II, a group of scientists has been attempting to understand the human nervous system and to build computer systems that emulate the brian's abilities. Many of the workers in this field of neural networks came from cybernetics; others came from neuroscience, physics, electrical engineering, mathematics, psychology, even economics. In this collection of interviews, those who helped to shape the field share their childhood memories, their influences, how they became interested in neural networks, and how they envision its future.
