Today’s Google Doodle celebrates what would have been the 107th birthday of computer pioneer Grace Hopper (1906-1992) just in time for the “Hour of Code” kicking off Computer Science Education Week.

Hopper created COBOL (Common Business-Oriented Language,) the program that allows computer to communicate through language as well as numbers. She joined the Navy Reserve in 1943, when she was teaching mathematics at Vassar, and finally reached the rank of rear admiral in 1985. Hopper, who repeatedly un-retired, became the oldest woman in the armed forces at the age of 76.

Hopper is credited with coining the term “bug in the system” because of the time she actually found a bug in a computer. As TIME described it in 1984:

She gets credit for coining the name of a ubiquitous computer phenomenon: the bug. In August 1945, while she and some associates were working at Harvard on an experimental machine called the Mark I, a circuit malfunctioned. A researcher using tweezers located and removed the problem: a 2-in. long moth. Hopper taped the offending insect into her logbook. Says she: “From then on, when anything went wrong with a computer, we said it had bugs in it.” (The moth is still under tape along with records of the experiment at the U.S. Naval Surface Weapons Center in Dahlgren, Va.)

She was also famous for her incredible work ethic and unique way of interpreting time. When teaching her students about nanoseconds, she would show them a length of wire that represented the distance electricity could travel in a nanosecond:

In her commencement speech to the Trinity College class of 1987, which was excerpted in TIME, she said:

There’s always been change, there always will be change . . . It’s to our young people that I look for the new ideas. No computer is ever going to ask a new, reasonable question. It takes trained people to do that. And if we’re going to move toward those things we’d like to have, we must have the young people to ask the new, reasonable questions. A ship in port is safe; but that is not what ships are built for. And I want every one of you to be good ships and sail out and do the new things and move us toward the future.
