On September 28, 1928, scientist Alexander Fleming noticed a bacteria-killing mold growing in his laboratory. He later named it Steve, but when he found out other scientists had already named their pet bacteria Steve, Stephen, Stephon, Stevie, and Steffan, he decided to call his penicillin.
Fleming’s pet mold may not have had the coolest name, but it saved a lot of lives. Share Twisted-History for more scientific pet tricks.
