Happy 107th Birthday, Grace Murray Hopper! The American computer scientist and U.S. Navy Rear Admiral (right) created Common Business-Oriented Language (COBOL), the program that allows computers to communicate through language and numbers. She is also credited with coining the term "debugging" in reference to fixing a computer. In addition to being a pioneer in the field, she paved the way for other females in computer science, including Katherine Yelick, left, who has built a career on predicting the needs and abilities of computer systems that haven't been invented. A University of California, Berkeley, computer science professor, Yelick also is the director for the National Energy Research Scientific Computing Center -- a high-performance Department of Energy computing facility that helps scientists run tests. One of the massive computers in the facility is named after Hopper.
