COMMENTARY: Karolinska Institutet (KI) takes its historical legacy seriously and has therefore taken several initiatives and implemented several measures, that some of the darker episodes in our history. We take these to be pressing issues, as discussed in an article in Dagens Nyheter on 18 July (E-DN 17 July). KI's more than 200-year history contains aspects that, from today's point of view, would be considered unethical, unscientific, undemocratic and, in some cases, racist.
