Miles walked this month: 82
‘Any girl can be glamorous. All you have to do is stand still and look stupid.’ Those are the words of Hedy Lamarr, a Hollywood star who was far from stupid. Between takes with Clark Gable and Spencer Tracy, Lamarr would work on inventions and during World War II she developed a frequencyhopping radio signal with composer George Antheil. The idea was that jumping frequencies would stop the enemy jamming signals, and it was later used in secure wifi, Bluetooth – and GPS. The US government responded by suggesting she use her celebrity to sell war bonds instead and despite filing a patent she never saw a cent from the invention, even though it’s now worth $30 billion. In fact, Lamarr’s contribution went unsung for decades, but I know I’ll think of the woman behind the tech when I next check my GPS on a walk.
