But Hopper was the first to identify a “bug” on the computer. Hopper’s colleagues at Harvard University in Cambridge, Massachusetts, found that his computer was constantly showing errors. When they opened the computer’s hardware to detect it, a kite was found. This trapped insect disrupted the computer’s electronics.
