Recently, Nova aired a program on Percy Julian. Julian was a black organic chemist who overcame everything blacks had to overcome in the early 1900's and went on to enjoy an extremely successful career as a chemist. He did remarkable work on steriods.
The Nova program was well done. I would have enjoyed a little more actual chemistry, but obviously the show was meant for a broader audience.
Stories like this always make me wonder, how many brilliant minds have we missed, lost or wasted because of bigotry, hatred and just plain stupidity. As brilliant as Julian was, he was certainly limited in what he accomplished. Not by his ability, but by the world he lived in. He did all of his steroid work at a paint company for crying out loud. Give this guy an endowed chair at a leading university and the world could be different today.
If you get the chance, watch a rerun or get the DVD. It's worth it.
