It's their award and they can make it in the likeness of H.P. Lovecraft's cat for all I care, but this is a very slippery slope to demonize and marginalize famous individuals who held beliefs or did actions that were not only considered acceptable, but downright normal, for the time in which they lived.
To give examples of people we should now remove from any sort of awards, building names, recognition, monuments, currency, etc., due to them having beliefs that were normal at the time but that we now see as barbaric or backwards:
-As many already mentioned, George Washington, Ben Franklin, and pretty much any of the original founders of the US (slave owners).
-Edgar Allen Poe (believed in phrenology, the now laughably bad science of believing head shape determined personality).
-Margaret Sanger, Alexander Graham Bell, Teddy Roosevelt (actually, pretty much any US President up until FDR), H.G. Wells, George Bernard Shaw, Winston Churchill, William Welch, and many more. All supported eugenics, the belief (among others) that Government should be allowed to forcibly sterilize "undesirables" to improve the human race's gene pool. Was considered to be largely to blame for the Holocaust and the idea of the Nazi "Aryan race".
There are too many anti-semites to even begin a list, not to mention it'd be real interesting if we got into what people would have likely believed. How many famous individuals from prior to 1950, no matter how 'progressive' they were for their time, would have supported gay marriage, states paying for sex change surgery, or affirmative action, back when
ideas such as these barely even existed? Obviously one cannot speak for the dead, but I'd have serious doubts.
Trying to transpose the morality of our age onto those who lived in a completely different era is a fool's errand. The way I see it, who's to say that 200 years from now, people won't look back at us and consider us barbaric because we kept dogs and cats as pets, or ate meat, or watched trashy reality shows?
