Navy Rear Admiral Grace Hopper was a pioneer in computer technology during World War II and one of the world’s earliest computer scientists.
Hopper told the story that the first computer “bug” was a real bug — a moth. At Harvard one August night in 1947, Hopper and her associates were working on the Mark II computer. When things were not working right, they checked out the machine and found the problem. Using tweezers, they removed a two-inch moth. From then on, when anything went wrong with a computer, they said “it had bugs in it.”
What if that had been a spider instead, or a mouse?
