Prepping the spring semester when classes start the day after an involuntary furlough is prone to put a particular professor perpetually a week behind. So forgive me for belatedly marking Martin Luther King, Jr. Day, which fell this year on Monday, January 18. Or we can say this is a more timely commemoration of yesterday's World Day for African and Afrodescendant Culture.
Of all the things one could relate about the legendary Dr. King, Nichelle Nichols (IMDb, PBS), Star Trek's original Lt. Uhura, has the very best story.
That's from the 2011 documentary, Trek Nation (IMDb, Amazon). She told the story also to the Television Academy Foundation in 2019.
