Age range 5+ To her adoring public, Hedy Lamarr was a glamorous movie star. But in private, she was something more: a brilliant inventor. Now Laurie Wallmark and Katy Wu, who collaborated on Sterling's critically acclaimed picture-book biography Grace Hopper: Queen of Computer Code, tell the inspiring story of how, during World War Two, Lamarr developed a groundbreaking communications system that still remains essential to the security of today's technology. 'Even readers who don't know Hedy Lamarr, 'the world's most beautiful woman,' will become fans after learning how she balanced her fame as a 1930s movie star with a passion for science and inventing.' - Booklist WINNER of the Cook Prize (Silver Medalist) WINNER of the Best Children's Books of the Year by Bank Street College 2020 FINALIST for a SCBWI's Crystal Kite Award, Atlantic Region
