One of my favorite STEM-themed pic­ture book biogra­phies is Hedy Lamarr’s Dou­ble Life: Hol­ly­wood Leg­end and Bril­liant Inven­tor by Lau­rie Wall­mark and Katy Wu. Here’s a brief description: To her ador­ing pub­lic, Hedy Lamarr was a glam­orous movie star, wide­ly con­sid­ered the most beau­ti­ful woman in the world. But in pri­vate, she was a bril­liant inventor. Dur­ing World War II, Hedy col­lab­o­rat­ed with anoth­er inven­tor to devel­op an inno­v­a­tive tech­nol­o­gy called fre­quen­cy hop­ping.
