Education

Stevenson studied at the Glasgow Mechanics Institution; College of Science and ArtsThe first Mechanics' Institution founded in Great Britain. Records of Glasgow Mechanics' Institution / College of Science and Arts (now the University of Strathclyde). He received his first tuition at the Mechanics Institution under his elder brother John Macadam after whom the Macadamia nut was later named.Edwin Macadam: http://www.shelwin.com/e/ancestry/macadam/macadam_history.htm#John%20Macadam,%20MD.

He received his doctorate (PhD) from Giessen University. Whilst in Germany he also spent some time working in the famous laboratory of Robert Bunsen.

John Macadam then became assistant to Dr. George Wilson, Lecturer in Chemistry at the University of Edinburgh College of Medicine and Veterinary Medicine from 1846 to 1847. The University of Edinburgh Medical School was then as now one of the world's preeminent medical centres of learning and from then on preeminent in the field of chemistry. Afterwards John Macadam returned to Glasgow for further medical studiesL.F.P.S., M.D., 1854; and F.F.P.S.G., 1855; K. F.
