Did you ever wonder why a computer bug is called a “bug”? In 1945, Grace Murray Hopper–who was the first female admiral in the Navy–was stationed at Harvard University. She had a computer programming background. When she was there, she wanted to help out the students and faculty fix a computer, so she walked inside of it (back then, the computers were HUGE, so you could actually step into them) and found an actual moth that was stuck in between two of the wires and shorted out the computer. Once they took the charred bug out, the computer was working fine with no problems.
Grace Murray Hopper taped the bug into her log book, which is now preserved in the Smithsonian Museum.
