Charley Darwin - wrote a book called "On The Origin of Species by Means of Natural Selection Or The Preservation Of Favored Races In the Struggle For Life" back in 1859. (Pictured below)
Charley's book was based on an idea he got from reading a paper by Tommy Malthus, a white supremicist who favored the extermination of "riff-raff" or "undesireables" in order to maintain the personal power and financial fortunes of the English aristocracy .
Tommy Malthus was another theoretical mathematician (like Al Einstien) who figured it was OK to exterminate "undesireable" members of society because they were all going to run out of food and starve to death anyway! So why not just prevent them from having children first or just kill them off?
His mathematical formulas 
became
very popular with the British aristocracy who exterminated lots
of English "rif-raff".
Later, a whole bunch of German psychiatrists
like Ernst Rudin, passed the idea along to other brilliant
thinkers like Adolph Hitler and members of his Nazi "good-ole"
Arian supremist boys club who came very close to killing off
everybody -- including themselves! These psychiatrists
personally supervised the extermination of millions of people!
The fences around the crematorium at the Auschwitz concentration camp where Germans carried out the theories of Tommy Malkmus, supervised by psychiatrists.
