the time. He demonstrated the process at the Cantor Lecture of the Royal Society of Arts, and after an uninspiring start (the control sample initially worked just as well as the one using his process) his work turned out to be a success. After the discovery of Insulin in 1922 Morgan became interested in medicinal chemistry, and he applied to West Ham Municipal College, where he studied for his Master of Science part-time while still working for the Gas Light and Coke Company. He finished his degree in 1925, and published his first paper in the Journal of the Chemical Society in 1926. One of his tutors while he was studying for his MSc was Arthur Harden, who impressed with his work advised Morgan to apply to The Lister Institute for Preventive Medicine for a Grocer's Company Research Student grant. He applied even though the pay (£250 a year) was less than that he was getting as a junior chemist, and was accepted by Charles Martin, the Institute director at the time. Morgan remained working there for over 50 years. Before taking up his position he did a variety of evening classes, including courses at the Case Technical Institute on the subjects of physiology and yeast microbiology and a course on biochemistry at Chelsea Polytechnic. While attending lectures at University College London he met Glen Anrep, who he worked for as an unpaid volunteer, thus getting the physiology qualification he needed to apply for a PhD. Work at the Lister Institute He initially worked with Dr Robert Robison identifying the structure of fructose 1,6-bisphosphatase discovered by Arthur Harden and William John Young. He succeeded in doing this, and studies on esters made up a large chunk of his PhD thesis. In 1925 he attended a course on organic microanalysis at the University of Graz on the recommendation of Harden. He was awarded his PhD in 1927 and the Beit Memorial Research Fellowship, which allowed him to continue his research on sugars. He visited Graz repeatedly in later years, and saw its transformation from the relative happiness of the 1920s to the oppressive regime in the 1930s, at one point being questioned by a Nazi patrol. In 1928 he was appointed as a biochemist at the institute's Serum and Vaccine Department north of London, where in 1930 he successfully immunised a horse against Poliomyelitis. He attended the 1929 International Physiological Congress
