A Nobel Prize laureate, Barry James Marshall is an Australian physician, who along with Dr Robin Warren made the historic scientific discovery, which stated the presence of bacterium Helicobacter pylori as the root cause for most peptic ulcers. The discovery came at a time when the world believed in the fact that stress, spicy foods, and too much acid caused peptic ulcer. It was a ground-breaking discovery as it helped in establishing the link between Helicobacter pylori infection and stomach cancer. Marshall was born in an average middle-class household. Since young, he displayed acumen for science and gained his Bachelor degree in Medicine and Surgery from University of Western Australia. He started his career as a physician but was soon inspired by the work of Dr Robin Warren, a pathologist interested in gastritis. Together their research led to the path-breaking finding that it’s the bacterium Helicobacter pylori (H. pylori) which causes most of peptic ulcers. For his outstanding work in the field of research, he was felicitated with numerous awards and honors.
