Rob Walters on spread spectrum: the Hollywood star and the mobile phone

Hedy Lamarr was the first woman to appear naked on film and a huge star in 1940s Hollywood. George Antheil was a piano player and composer. So how did this unlikely couple also invent the latest technology used by Wi-Fi and Bluetooth? Mobile technology expert and WiO member Rob Walters will explain all on Thursday next week, 12 November, at 7.30 pm. The event is part of the Science Oxford Live series (, 01865 810000. Tickets are £3 unless you qualify for a concession, in which case they are free, and booking is said to be “recommended”.
