NEW YORK (AP) — If you’re a fan of Hidden Figures and Margot Lee Shetterly’s story of three black female mathematicians’ contributions to the space program, you should thank in part the efforts of the Alfred P. Sloan Foundation. “We made a grant to Margot Lee Shetterly when she was unknown,” said Doron Weber, a vice president and program director at the foundation and a winner this year of an honorary National Book Award. “First I had to find out if it was true, because it was such an amazing story. And the question after that was whether she had the chops to do it because she had never done a book before. She did, and she wrote a beautiful book.”
