Caltech announced Friday that it would remove the name of its founding president and first Nobel laureate, Robert A. Millikan, from campus buildings because he supported eugenics — joining universities across the nation in repudiating those who joined the racist movement a century ago. “It is fraught to judge individuals outside of their time, but it is clear from the documentation presented that Millikan lent his name and his prestige to a morally reprehensible eugenics movement that already had been discredited scientifically during his time,” Caltech President Thomas F. Rosenbaum said in a statement. “The renamings will help position the Institute to retain and attract the most talented and innovative researchers from every background, so we may remain a leader in science and technology.”
