Who might take note here?

As a visiting professor at King’s College London he would regale students with stories of Stalinist Russia, the American Civil War (another passion), Peru’s revolutionary Communist Party (the Shining Path) and much else of seeming irrelevance that by some ingenious tangential device he would bring to bear on investor-state arbitration. He never used the title professor, once claiming to a colleague that he was so fed up with other people using titles to promote themselves that he was searching online to purchase a doctorate.
