The most amazing part was how long ago women like Vaughan were able to break through barriers to excel in mathematical and scientific fields! I knew that women had made some strides in employment in the 1930s, and that there were lots of opportunities during the war, but many women were forced out of "men's positions" after the war was over. The intrepid women in this book managed to hang on to their positions. The other noteworthy part was how they managed to raise children while working long hours during a time when child care was not as readily available.
Not only is Hidden Figures an interesting book to read for pleasure, but it is also a very useful title when researching women's history or African American history. Hidden Figures joins Blumenthal's Let Me Play, Macy's Wheels of Change and Farrell's Pure Grit as a must read for girls who want to investigate women who fought for opportunities even when they came with a high price.
