Rear Admiral Grace Murray Hopper

In 1943, during World War II, she joined the United States Naval Reserves. She was assigned to the Bureau of Ordinance Computation Project. There she became the third programmer of the world's first large-scale computer called the Mark I. When she saw it, all she could think about was taking it apart and figuring it out. "That was an impressive beast. She was fifty-one feet long, eight feet high, and five feet deep," said Hopper. She mastered the Mark I, Mark II, and Mark III. While trying to repair the Mark I she discovered a moth caught in a relay. She taped the moth in the log book and from that coined the phrase "a bug in the computer".
