Just over a year ago, when we were celebrating the 50th anniversary of the first Moon landing, I talked about the lack of diversity in space and mentioned Mary Jackson. In 2016, the movie Hidden Figures shared the stories of Mary Jackson and two other Black female mathematicians – Katherine Johnson and, Dorothy Vaughan. They worked at NASA when a ‘computer’ still meant a person carrying out mathematical calculations. The film is based on a book by Margot Lee Shetterly, which I am reading at the moment. The book offers a more detailed and accurate account of the prejudice these women (and others) had to overcome.
