I just came across this wonderful video clip of Rear Admiral (retired) Grace Hopper on the Letterman show. Who is she you ask? Grace Hopper is one of the most famous women in the history of computing. She programmed the Harvard Mark 1 during WWII. She discovered the first computer bug, literally a moth that had got caught in a relay. She programmed the UNIVAC after the war and developed the first high-level programming language, FLOW-MATIC, which was the basis for COBOL. As a necessity she also had to invent the first compiler to translate FLOW-MATIC code into machine code. Semi-retired she consulted for many computing companies and she has a US naval destroyer named in her honor. A truly remarkable woman.
