0:00 On September third, 1928, a bacteriologist named Alexander Fleming got back from vacation to his notoriously messy lab at St.0:09 Mary's Hospital in London.0:10 It's the perfect setup for the kind of story we talked about last week, Admin—that potent mix of rivalry, obsession, and just pure, dumb luck that drives so many breakthroughs.0:23 Right.0:24 And in this case, the "luck" was a stray mold spore that had drifted in through an open window and landed on a petri dish full of staph bacteria he'd forgotten to clean up.0:36 Exactly.0:37 And everywhere else on the dish, the bacteria grew in a thick, opaque film.0:42 But around this one patch of fuzzy, greenish mold… there was a clear, dead zone.0:48 A circle of nothing.0:49 Most people would have just thrown it out.0:52 Annoying contamination.0:54 But Fleming looked at it and his first thought was, reportedly, "That's funny." He realized the mold was secreting something that KILLED the bacteria.1:05 He called it "mould juice." "Mould juice." Not quite as catchy as penicillin.1:10 Not quite.1:11 He eventually named it penicillin, and he published a paper on it in 1929.1:17 But here’s the turn.1:18 He couldn't stabilize it.1:20 He couldn't purify it.1:21 And when he presented his findings… nobody cared.1:25 The scientific community basically shrugged.1:28 So for ten years, one of the most important discoveries in human history just… sits there.1:35 It’s a footnote in a forgotten journal.1:37 It almost died.1:39 It almost did.1:40 Until a decade later, at Oxford University.1:43 A team led by an Australian pathologist, Howard Florey, and a brilliant, volatile German-Jewish refugee biochemist, Ernst Chain, stumble across Fleming's old paper.1:55 And these two were NOT like Fleming.1:57 Florey was this driven, ambitious, almost grim organizer.2:01 Chain was the temperamental genius.2:04 They didn't even particularly like each other.2:07 No, they didn't.2:08 But they shared an obsession.2:10 They saw the potential Fleming had missed—or, at least, the potential he couldn't unlock.2:17 They decided they were going to be the ones to isolate this "mould juice." And their work was just… grueling.2:25 I mean, this is the "agony" part of the show title, right?2:29 They're trying to grow this finicky mold in anything they can get their hands on during wartime rationing.2:37 Hospital bedpans, biscuit tins, whatever.2:40 They even hired "penicillin girls" to manage the vats.2:43 And after months of this, they finally scraped together enough of a brownish, impure powder to test on a single human being.2:52 Albert Alexander.2:54 A 43-year-old policeman.2:55 And his initial injury was so… small.2:58 A scratch from a rose thorn in his garden.3:01 It got infected.3:02 Sepsis spread all over his body.3:05 Abscesses on his face, in his lungs.3:07 He was in the Radcliffe Infirmary, dying.3:10 And they give him the penicillin.3:13 And what happens?3:14 A miracle.3:15 Within 24 hours, his fever drops.3:17 He starts eating.3:18 The infection starts to retreat.3:20 It’s working.3:21 It’s actually, unbelievably working.3:24 But then the nightmare starts.3:26 They run out.3:27 They run out.3:28 They had so little of it.3:30 They were literally collecting his urine, taking it back to the lab, and desperately trying to extract the unmetabolized penicillin to put back into his IV.3:41 But it wasn't enough.3:43 The bacteria came roaring back.3:45 And after five days, Albert Alexander died.3:48 Wow.3:48 To be that close… to see the cure and have it slip through your fingers.3:54 But that failure was also the proof, wasn't it?3:57 It was EVERYTHING.3:58 It proved the drug worked in a human.4:01 They just needed more of it.4:03 A LOT more of it.4:04 And that tragedy is what convinced the British government, and then the American government, to go all-in.4:12 World War Two was raging, and infected wounds were killing more soldiers than bullets were.4:18 So that's when it goes from a lab curiosity to an industrial project.4:23 Florey flies to the U.S.4:25 with his sample.4:26 Right.4:27 To Peoria, Illinois, of all places.4:29 They find a better, more productive strain of the mold on a cantaloupe from a local market.4:36 And companies like Pfizer and Merck figure out how to mass-produce it in these huge, deep-fermentation tanks.4:44 By D-Day in 1944, there was enough penicillin to treat every single wounded Allied soldier.4:50 It's such a clear example of that pattern we see over and over.4:55 Fleming had the Eureka moment—the spark.4:58 But it took the obsessive agony of Florey and Chain's team, and the crisis of a world war, to actually turn that spark into a fire that changed everything.5:09 It really makes you wonder, doesn't it?5:12 How many other life-saving "mould juices" are out there, sitting in forgotten journals, just waiting for the right kind of obsessive to come along?
