Happy birthday to Grace Hopper, a computer scientist and  Rear Admiral in the United States Navy.Today on the Google home page, Grace Hopper is remembered on her 107th birthday. What did she do to earn a special doodle on Google?

Grace worked on the Mark 1 computer at Harvard University, the first computer ever! She was in charge of programming it. At the time noone believed computers would ever be able to communicate with words since they were programmed with numbers only. But Grace changed that by developing a language for computers so they could "speak" English and use numbers. Her program eventually became the COBOL programming business language used today.

She was also the one who coined the phrase "a bug in the system" because while working on the Mark 1, a co-worker discovered a moth within the computer. This "bug" caused one of the circuits to malfunction. Grace took the moth and taped it into her logbook. This page along with her records on the first computer  is on display at the U.S. Naval Surface Weapons Center in Dahlgren, Va.

By the way, this machine does not resemble the computers we see today. Instead, it was almost as long as a semi-truck's trailer, 51 feet, 8 feet tall, and 8 feet wide.
