> The future programming pioneer, Grace Murray Hopper was born December 9, 1906 in
> New York, New York, USA. Grace enjoyed
> playing with machines when she was a young girl. She took apart several alarm
> clocks owned by her family to see how they were put
> together inside. She spent lots of time building strange vehicles with her
> Structiron kit. Her grandfather, John Van Horne was a surveyor
> for New York City. She sometimes helped him hold his surveyor's pole when he was
> planning new streets. She learned about angles,
> curves and intersections. She was a very good student in school and was
> accustomed to be at the head of her class. When asked about
> influences in her life, she said, "My mother's very great interest in mathematics
> and my father's, a house full of books, a constant
> interest in reading, and insatiable curiosity... these were a primary influence
> all the way along."
>
> In 1924 Grace enrolled in Vassar College in Poughkeepsie, New York. She majored
> in math and physics. In her senior year in college,
> she was elected to Phi Beta Kappa, an honorary society for students with top
> grades. She won Vassar College Fellowship which
> provided money for further education. After graduating in 1928, she enrolled in
> Yale University in New Haven, Connecticut to earn a
> master's degree in mathematics. After receiving her degree in 1930, she married
> Vincent Hopper, an English instructor at New York
> University, whom she had dated for a couple of years.
>
> After returning from her honeymoon in Europe, Grace accepted a position at Vassar
> as a math instructor. Her teaching methods were
> rather unusual. She tried to show the role mathematics plays in real life by
> showing concrete examples. In her probability course, she
> required her students to play bridge and to play dice games. She then had them
> predict results. In another course, she had them plan a
> city, figure out the expense of running it and where to get the money to cover
> those expenses. She sometimes gave out final test exams
> at the beginning of the course, so her students would know what they were
> expected to learn. Grace continued her own education as
> well, and in 1934, she earned a Ph.D degree in mathematics from Yale.
>
> Grace's great-grandfather, Alexander Russell, and her personal hero had been a
> rear admiral in the U.S. Navy. So when the United
> States became involved in World War II, Grace hoped to join the Navy as well.
> However, at that time, the Navy did not accept women
> candidates. By 1943, when there was a shortage of men who could serve, the Navy
> started accepting women into WAVES (Women
> Accepted for Voluntary Emergency Service). The recruiting posters said, "Enlist
> in the WAVES- Release a Man to Fight at Sea." Grace
> was eager to join, but she was turned down. They said that at 36, she was too
> old, she didn't weigh enough and being a teacher, she was
> needed elsewhere to teach future soldiers and sailors. Grace, therefore, took a
> leave of absence from Vassar and returned to the
> recruitment office. She convinced them to accept her. She was sworn in in 1943
> and started officer training. She graduated at the top of
> her class from Midshipman's School in 1944 as Leutenant JG (Junior Grade) Grace
> Murray Hopper. She was immediately assigned to
> work at the Bureau of Ordnance Computation Project. She was going to work with
> computers at Harvard University under the direction
> of Howard Aiken.
>
> Her first computer was the Mark I. Grace was to use it to compute firing tables
> for weapons. She obtained mathematical formulas for
> firing tables, then wrote them as a series of instructions for the computer to
> follow. Those instructions were then translated into binary
> code (a system which uses only two digits, 0 and 1) that the computer can
> understand. These were delivered as punched holes in reels
> of paper. Punched holes were 1's and were read as switch ON, allowing the current
> to flow through. Zeros were covered and were read
> as switch OFF and the current would not flow. Although this was laborious work,
> once the computer was programmed, it could perform
> the same computations quickly and many times over, saving time in the long run.
> In 1946 Grace Hopper published a book A Manual of
> Operations for the Automatic Sequence Controlled Calculator.
>
> In 1945 Grace and Vincent divorced. They had no children. Grace continued her
> work with the Mark II and Mark III. She hoped to
> write computer programs that would allow other scientists and eventually
> non-scientists to use computers directly, instead of having to
> depend on computer specialists to do this for them. Her colleagues told her it
> wouldn't happen, because only scientists had the necessary
> knowledge to use computers. Grace was determined to make computers accessible to
> many other people in the future. In 1949 she left
> Harvard and started working at Eckert-Mauchley Computer Corporation in
> Philadelphia, Pennsylvania. She joined the team working on
> construction of the Universal Automatic Computer, Univac I. It used vacuum tubes
> instead of electromechanical relay switches and was
> to be twenty times faster than the Mark III. It also had internal memory.
>
> Her original staff comprised four men and four women. Grace liked hiring women.
> She said, "Women turn out to be very good
> programmers for one very good reason. They tend to finish up things, and men
> don't very often finish." Her next goal was to get the
> computer to translate its own codes and call on preprogrammed subroutines when
> needed. She finished the program in 1952 and called it
> the A-0 compiler. That same year the Navy promoted her to lieutenant commander.
> She then started working on a program that would
> be used for business-oriented tasks. By 1955 she finished the code with twenty
> business commands, such as "count" and "display". Her
> program named FLOW-MATIC became a model for a new program COBOL (COmmon Business
> Oriented Language), which was
> developed by a team of programmers while Grace Hopper was one of the advisors for
> the team. She was later referred to as
> Grandmother of COBOL.
>
> In 1966 Grace was promoted by the Navy to commander, but she had reached the
> legal limit of twenty years for serving as a reservist
> and on December 31, 1966, she retired. Within six months the Navy officials
> decided they needed Grace back to work with COBOL, so
> they asked her to come back on temporary duty, which was later changed to
> "indefinite". Her new job was to combine various versions
> of COBOL into USA Standard COBOL. She was known among her coworkers as "Amazing
> Grace", or "a little old lady who talks to
> computers." Her office had a skull-and-crossbones flag and a wall clock that ran
> backwards. This was to remind people to be flexible in
> their thinking.
>
> She was one of two women named fellow of the Institute of Electrical and
> Electronics Engineers and in 1979 she won IEEE's McDowell
> Award. In 1985, Grace Hopper was appointed rear admiral by President Ronald
> Reagan. In 1986, she retired again from the Navy, this
> time for good. She was the nation's oldest military officer on active duty. After
> her retirement from the Navy she accepted a position
> with Digital Equipment Corporation as senior consultant, where she remained until
> her death. In 1991 President George Bush awarded
> her the National Medal of Technology. She was the first individual to receive it.
>
> Grace Hopper died in her sleep on January 1, 1992, at the age of eighty-five. She
> was buried at Arlington National Cemetery, Virginia
> with a full Navy funeral. She kept on receiving honors even after her death. In
> 1994 she was inducted into National Women's Hall of
> Fame and the Navy announced that they would name a guided missile destroyer USS
> Hopper. --

Let not the fierce sun dry one tear of pain before thyself
hast wiped it from the sufferer's eye.
