The Renegade Doctor Who Drank Bacteria and Won a Nobel Prize

For years, Australian physician Barry Marshall witnessed ulcer patients suffering immensely, even dying. He hypothesized, and ultimately proved, that the persistent bacteria Helicobacter pylori, not stress, was the culprit. To demonstrate this groundbreaking conclusion, he ingested a bacterial culture, experiencing gastritis firsthand. His work earned him a Nobel Prize, revolutionizing ulcer treatment and pioneering the use of weakened Helicobacter for flu vaccines. His story underscores the importance of challenging authority, pursuing truth, and maintaining an open mind about the unknown.
