Google on Monday posted a special doodle on its homepage to celebrate the 107th birth anniversary of Navy Rear Admiral Grace Murray Hopper, who is credited with pioneering computer programming language.

Born on December 9, 1906, Ms. Hopper is also credited with popularizing the term "debugging" after spotting a real moth in her computer.

According to Ms. Hopper's Navy history page, she had found the bug trapped in the Mark II Aiken Relay Calculator when it was being tested at Harvard University in September 1947. She later wrote that they had 'debugged' the gadget.

Ms. Hopper was a graduate from Yale University. She was later trained as a physicist and mathematician, which enabled her to join the U. S. Navy Reserves in 1943. The World War II had forced the U. S. military to recruit women into the military.

In the year of 1952, she invented the A-0, the first software compiler that created machine code from mathematical instructions.

Following the Second World War, Ms. Hopper returned to the private sector and started working on the Univac computing platform. However, she kept working with the Navy Reserves till 1986, when she retired as Rear Admiral.

Ms. Hopper passed away on January 1, 1992, at age of 85.
