Today's Google doodle commemorates computer pioneer Grace Hopper, who invented key software technologies that paved the way for modern day computer languages.

She managed to get government agencies and industry to agree on a common business programming language, named Cobol.

Her work remains part of everyday life, when you withdraw money from a cash machine a Cobol program is used.

But what do we know about her?

Here are the top 10 facts about Grace Hopper and her work.

10. She has dozens of various places, objects and organisations named after her.

These include the U.S. Navy destroyer USS Hopper, the Cray XE6 "Hopper" supercomputer at  NERSC and the Department of Energy's flagship computer system "Hopper".

9.  She was curious about mechanics from an early age.

At the age of seven she decided to determine how an alarm clock worked, and dismantled seven alarm clocks before her mother realised what she was doing.

8. She retired from the navy at the standard age of 60, but was repeatedly recalled until her eighties.

She was recalled to active duty in August 1967 for a six-month period that turned into an indefinite assignment.

She again retired in 1971, but was asked to return to active duty again in 1972.

7. Owing to the breadth of her accomplishments and her naval rank, she is sometimes referred to as Amazing Grace.

6. At a celebration held in Boston on the USS Constitution to celebrate her final retirement, Hopper was awarded the Defense Distinguished Service Medal, the highest non-combat decoration awarded by the Department of Defense.

5. At the time of her retirement, she was the oldest active-duty commissioned officer in the United States Navy (79 years, eight months and five days).

Coincidently, she was aboard the oldest commissioned ship in the United States Navy (188 years, nine months and 23 days).

4. Women at the world's largest software company, Microsoft, formed an employee group called Hoppers and established a scholarship in her honor.

Hoppers now has over 3000 members worldwide.

3. Hopper is credited with popularizing the term "debugging" for fixing computer glitches.

While she was working on a computer in 1947, her associates discovered a moth stuck in a  relay and thereby impeding operation, whereupon she remarked that they were "debugging" the system.

The remains of the moth can be found in the Smithsonian Museum, in Washington DC.

In front of the River House Apartments, the park was originally funded by private sources, but in later years, it became an official park of Arlington County.

1. One of Hopper's most famous quotes, which is often attributed to others, is: "It's easier to ask forgiveness than it is to get permission."
