Hedy Lamarr was a curious girl, full of ideas and questions. As a young woman she became a famous actress, admired by everyone for her beauty. But behind that image there was a brilliant mind, able to observe, imagine and invent. Throughout her life, Hedy devised a revolutionary system, frequency hopping, which many years later would give rise to fundamental technologies such as Wi-Fi and Bluetooth. For a long time her talent was ignored, but she never stopped thinking and creating. This book is part of the “Little Great Heroes” collection, designed for girls and boys who are beginning to read.
