Career
Black had large debts upon his graduation from university, so took a teaching job in Singapore for three years, before moving to London in 1950. Upon his return to Scotland in 1950, he joined the University of Glasgow (Veterinary School) where he established the Physiology Department and developed an interest in the way adrenaline affects the human heart, particularly those suffering from angina. Having formulated a theory to annul the effects of adrenaline, he joined ICI Pharmaceuticals in 1958, remaining with the company until 1964, during which time he developed propranolol, which later became the world's best-selling drug. During this time Black pioneered a method of research whereby drug molecules were purposefully built instead of being synthesised first and then investigated for their potential medical uses. The discovery of propranolol was hailed as the greatest breakthrough in the treatment of heart disease since the discovery of digitalis.
At the same time, Black was developing a similar method of treatment for stomach ulcers, but ICI did not wish to pursue the idea so Black resigned in 1964 and joined Smith, Kline and French for whom he worked for nine years until 1973. While there, Black developed his second major drug, cimetidine, which was launched under the brand name Tagamet in 1975 and soon outsold propranolol to become the world's largest-selling prescription drug.
Black was appointed professor, and head of department, of pharmacology at University College London in 1973 where he established a new undergraduate course in medicinal chemistry but he became frustrated by the lack of funding for research and accepted the post of director of therapeutic research at the Wellcome Research Laboratories in 1978. However he did not agree with his immediate boss there, Sir John Vane, and resigned in 1984. Black then became Professor of Analytical Pharmacology at the Rayne Institute of the King's College London medical school, where he remained until 1992. He established the James Black Foundation in 1988 with funding from Johnson and Johnson and led a team of 25 scientists in drugs research, including gastrin inhibitors which may prevent some stomach cancers.
Black contributed to basic scientific and clinical knowledge in cardiology, both as a physician and as a basic scientist. His invention of propranolol, the beta adrenergic receptor antagonist that revolutionised the medical management of angina pectoris, is considered to be one of the most important contributions to clinical medicine and pharmacology of the 20th century. Propranolol has been described as the greatest breakthrough in heart disease treatments since the 18th century discovery of digitalis and has benefited millions of people. Black's method of research, his discoveries about adrenergic pharmacology, and his clarification of the mechanisms of cardiac action are all strengths of his work.
He was greatly involved in the synthesis of cimetidine, at the time a revolutionary drug for the treatment and prevention of peptic ulcers. Cimetidine was the first of a new class of drugs, the H2-receptor antagonists.

Famous quotes containing the word career:
“What exacerbates the strain in the working class is the absence of money to pay for services they need, economic insecurity, poor daycare, and lack of dignity and boredom in each partner’s job. What exacerbates it in upper-middle class is the instability of paid help and the enormous demands of the career system in which both partners become willing believers. But the tug between traditional and egalitarian models of marriage runs from top to bottom of the class ladder.”
—Arlie Hochschild (20th century)
