Happy 107th Birthday, Grace Murray Hopper! The American computer scientist and U.S. Navy Rear Admiral (right) created Common Business-Oriented Language (COBOL.) She also coined the term "debugging" in reference to fixing a computer. She paved the way for other females in computer science, including Katherine Yelick, left, a University of California, Berkeley, computer science professor, and director for the National Energy Research Scientific Computing Center -- a high-performance computing facility that helps scientists run tests. One of the computers in the facility is named after Hopper. Click through the gallery for more women pioneers in science, technology, engineering and mathematics.
