Dr David Yellowlees was the Physician Superintendent of the Glasgow Royal Asylum (Gartnavel) from 1874 to 1901. He also held the post of Lecturer in Insanity at the University of Glasgow from 1880.

A controversial figure in his day, Yellowlees was an advocate for using restraint in certain patient cases at Gartnavel, despite the majority of asylums moving away from this method. ]]>
