The first computer bug was a literal bug.

To be exact, a moth.

On Sept 9, 1947, a moth got trapped in Harvard University's Mark II computer -- causing multiple errors.

This bug disrupted the electronics inside the Mark II.

Here's a photo of that first computer bug.

@atomicpoet Admiral Grace Hopper who found the first "bug" was an amazing technologist and doesn't get the recognition she deserves imho. One of my IT heros!
