I saw the movie, so very well done, and the Medal of Freedom ceremony. It was certainly well deserved and long past time she received the recognition for her brilliant work! She's a heroine for our time - or any time! 
And I'm so glad that Katherine Johnson is still with us to finally receive the recognition she deserved. I just wish it had happened sooner since Mary Jackson and Dorothy Vaughn were equally deserving, but at least they have a legacy now. I thought all three actresses who played them were just excellent... 
Loved the movie, three! The cast and music was outstanding.
The ladies weren't included in our school textbooks, but glad to see them getting some shine for their impact on a major historical event.
I'm old enough to remember the early space flights. Each one was a major event and we followed all of them closely - we even watched them on TV in elementary school if one of them took place while we were in school. But, of course, all the attention was on the astronauts, we knew all of their names. No one paid much attention to what went on behind the scenes or what it took to get them in the air - from the perspective of a kid. We sometimes saw the guys in the control room, but that was as far as it went. But remembering those days, it was fascinating to learn the background and all the work it really took - and these were the brilliant and hard working women responsible! I loved learning all about them and it sure took a great deal. They're my heroines now... 
The first space flight I remember was Challenger. Like you, we knew their names and would later learn more (as we got older) about how/who/why the tragedy happened. Like that mission, and all the others that came after, all the attention was on the astronauts then (and now).
In "Hidden Figures", it was fascinating to learn more about these ladies behind the scenes, and the workplace environment in the 1960s. They definitely are my heroines and glad that their stories getting mad props. to you.
