Alexander Fleming Museum

The Alexander Fleming Laboratory Museum occupies the very space where the course of modern medicine shifted forever. You are standing within the original, cramped laboratory at Saint Mary's Hospital where Alexander Fleming conducted his research in the early twentieth century. The room is preserved to mirror the exact conditions of September 1928, the moment a stray mold spore drifted into a petri dish and changed the world. This small, dusty environment serves as a time capsule of a pre-antibiotic era, offering a stark contrast to the medical miracles that would soon emerge from this unlikely discovery. It stands as a testament to the power of a prepared mind observing a chance accident, forever linking this quiet corner of Paddington to the survival of millions of people worldwide.
