Sloan Foundation book committee and with Sloan programs vice president Doron Weber. A grant from the foundation supported the work of research.Hedy Lamarr’s daughter, Denise Loder-DeLuca, was generous with her time and enthusiasm. Sheila Weller introduced us. Hedy’s son, Anthony Loder, scanned vital documents for me and reviewed them with me at a time of grave illness. I value their confidence and hope that the result warrants it.Nino Amarena, inventor, electrical engineer, and man for all seasons, tutored me in hydrogen peroxide technology, radio control, frequency hopping, the pleasures and frustrations of invention, and much more. His knowledge and guidance have been invaluable.Dave Hughes gave me a day and evening to explore his nomination of Hedy for an Electronic Frontier Foundation award and his own electronic pioneering. Susi Maurer not only guided me around Vienna but also located and drove me to one of Fritz Mandl’s hunting lodges, where we peered in windows and interviewed locals who remembered stories their parents told them of Hedy’s isolation and loneliness there.
