Grace Hopper

    US Navy Rear Admiral Grace Brewster Hopper
   (1906-12-09 to 1992-01-01), née Grace Brewster Murray.

   Hopper is believed to have concieved the concept of the
   compiler with the A-0 in 1952.  She also developed the
   first commercial high-level language, which eventually
   evolved into COBOL.  She worked on the Mark I computer
   with Howard Aiken and with BINAC in 1949.

   She is credited with having coined the term "debug", and the
   adage "it is always easier to ask forgiveness than it is to
   get permission" (with various wordings), which has been the
   guiding principle in sysadmin decisions ever since.

   See also the entries debug and bug.

   Hopper is buried at Arlington National Cemetery.  In 1994, the
   US Navy named a new ship, the guided-missile destroyer USS
   Hopper (http://hopper.navy.mil/), after her.
