The history of gastritis begins with the discovery of curved bacteria, now called H. pylori, by Dr. A. Stone Freedberg in the 1940s. Discouraged by the science community and dissuaded by work done by Dr. Eddy D. Palmer, Dr. Freedberg gave up this line of work and pursued a career largely in cardiology. 

However, in 1984, Dr. Barry J. Marshall and Dr. J. Robin Warren noted H. pylori among patients with ulcers. These researchers connected the H. pylori infection to chronic gastritis symptoms, like peptic ulcers. And thus, they were awarded the Nobel Prize in Physiology or Medicine in 2005 for their discovery of “the bacterium Helicobacter pylori and its role in gastritis and peptic ulcer disease.”
