Dorothy Vaughan had six children, so it was really hard to commit to them and science at the same time. But this reconciliation was, in her case, a philosophical matter of private and public interest.

As a mother, she naturally missed her children and wanted to spend more time with them; but she had this other mission as well, which was even more important, in terms of humanity.
