On September 28, 1928, Alexander Fleming accidentally discovered penicillin. He was investigating the properties of staphylococcus bacteria and, after returning from a vacation, discovered that one culture had been contaminated by a mold, and the bacteria surrounding the mould had been killed. Fleming named the mold’s secretions penicillin, and discovered that it was effective against a number of diseases. He was awarded the Nobel prize in 1945 for his discovery.
This comes from an intriguing new blog called Picture This Date which aims to inform us about history while also examining the role of image-making in defining how we remember events from the past. From the About section:
There are some events that are photographed because they’re important. Others become important because of the way they’re photographed. Both kinds of events are eligible to appear on this site. There are dozens of other websites describing “this day in history”, and I have no intention or hope of competing with them: in fact, this site is indebted to all of them. But none of them, as far as I know, focus on the visual…Events will be selected based on historic importance, but also based on the quality and character of the imagery related to it.
