(p. 103) Barry Marshall, a lanky twenty-nine-year-old resident in internal medicine at Warren’s hospital, was assigned to was assigned to gastroenterology for six months as part of his training and was looking for a research project. The eldest son of a welder and a nurse, Marshall grew up in a remote area of Western Australia where self-sufficiency and common sense were essential characteristics. His personal qualities of intelligence, tenacity, open-mindedness, and self-confidence would serve him and Warren well in bringing about a conceptual revolution.

Indeed, the concept that bacteria caused stomach inflammation, and even ulcers, was less alien to him than to most gastroenterologists.
