The First Computer Bug Was Actually A Dead Bug

  • The First Computer Bug Was Actually a Dead Bug. We know a computer bug is known as an error or a fault due to a flaw in the computer program or system.
  • The first person to use the word “bug” to describe a technological error was Thomas Edison.
On September 9, 1947, the first actual incident of a computer bug was recorded. It was recorded by Grace Hopper, an American computer scientist, and member of the U.S. Navy. She was working on a Harvard Mark II computer and recorded the bug in the computer’s logbook.

After she noticed a hindrance in the computer’s operation, she started tracing the problem. Hopper found a dead moth that was stuck between the relay contacts of the computer. She removed the moth and taped it into Mark II’s Log. Beneath the moth, she wrote “First actual case of bug being found.”

Although there are some claims that other people found the moth in the computer, Hopper remains the one who did the logbook entry.

So this is the story of the first computer bug.
