Alexander Scrimger was amongst the first Regents to be employed by Edinburgh University. He began work in October 1586, assuming responsibility for that year's First Year (or 'Bajan') class. Under the regenting system then prevalent in Scottish universities, Scrimger was due to remain with the 1586 intake throughout their four-year Master of Arts degree, tutoring them in all subjects. He left the University, however, at the end of their third year of study in 1589. According to Thomas Craufurd, he was removed 'in a quiet maner [sic]' by Robert Rollock, the Principal, 'for some maleversation [misconduct] in a mutinie of his scholars'.
