What do you want to be when you grow up? When Katherine Johnson was young, women weren't expected to go into the math and science fields. Johnson loved math, but she never thought she could be a mathematician. After studying math in school and teaching for a few years, she learned that the organization that would later become NASA was hiring women to complete mathematical equations.
