  In 1815 Hope was elected as president of the Royal College of Physicians of Edinburgh (1815–19), and as vice-president of Royal Society of Edinburgh (1823–33) during the presidencies of Walter Scott and Thomas Makdougall Brisbane.
  Charles Darwin was one of Hope's students, and Darwin viewed his chemistry lectures as highlights in his otherwise largely dull education at the University.
