'''Grace Brewster Hopper''' ({{née|'''Murray'''}}; December 9, 1906 – January 1, 1992) was an American [[computer scientist]], [[mathematician]], and [[United States Navy]] [[Rear admiral (United States)|rear admiral]].<ref>{{cite news |last=Cantrell |first=Mark |date=March 1, 2014 |title=Amazing Grace: Rear Adm. Grace Hopper, USN, was a pioneer in computer science |url=http://content.yudu.com/A2qfj4/201403March/resources/3.htm |magazine=Military Officer |publisher =Military Officers Association of America |volume=12 |issue=3 |pages=52–55, 106 |access-date=March 1, 2014}}</ref> She was a pioneer of computer programming. Hopper was the first to devise the theory of machine-independent programming languages, and used this theory to develop the [[FLOW-MATIC]] programming language and [[COBOL]], an early [[high-level programming language]] still in use today. She was also one of the first programmers on the [[Harvard Mark I]] computer. She is credited with writing the first computer manual, "A Manual of Operation for the Automatic Sequence Controlled Calculator."

Before joining the Navy, Hopper earned a Ph.D. in both mathematics and mathematical physics from [[Yale University]] and was a professor of mathematics at [[Vassar College]]. She left her position at Vassar to join the [[United States Navy Reserve]] during World War II. Hopper began her computing career in 1944 as a member of the Harvard Mark I team, led by [[Howard H. Aiken]]. In 1949, she joined the [[Eckert–Mauchly Computer Corporation]] and was part of the team that developed the [[UNIVAC I]] computer. At Eckert–Mauchly she managed the development of one of the first [[COBOL]] compilers.

She believed that programming should be simplified with an English-based computer programming language. Her compiler converted English terms into [[machine code]] understood by computers. By 1952, Hopper had finished her program [[Linker (computing)|linker]] (originally called a [[compiler]]), which was written for the [[A-0 System]].<ref name="Spencer85">{{cite book|title=Computers and Information Processing|publisher=C.E.

In 1959, she participated in the [[CODASYL]] consortium, helping to create a machine-independent programming language called [[COBOL]], which was based on English words. Hopper promoted the use of the language throughout the 60s.

The U.S. Navy {{sclass|Arleigh Burke|destroyer|0}} guided-missile destroyer {{USS|Hopper}} was named for her, as was the [[Cray XE6]] "Hopper" supercomputer at [[NERSC]],<ref>{{Cite web |title=Hopper |url=http://www.nersc.gov/users/computational-systems/retired-systems/hopper/ |website=National Energy Research Scientific Computing Center |language=en-US |access-date=March 19, 2016 |archive-date=March 14, 2016 |archive-url=https://web.archive.org/web/20160314142943/http://www.nersc.gov/users/computational-systems/retired-systems/hopper |url-status=dead}}</ref> and the Nvidia GPU architecture "[[Hopper (microarchitecture)|Hopper]]".<ref>{{Cite web | title=NVIDIA GH200 Grace Hopper Superchip | url=https://www.nvidia.com/en-us/data-center/grace-hopper-superchip/ |access-date=2024-05-25}}</ref><ref>{{Cite news |last=Helmore |first=Edward |date=2024-02-23 |title='Amazing Grace': the name behind Nvidia's $2tn chip empire |url=https://www.theguardian.com/technology/2024/feb/23/grace-hopper-nvidia-superchip |access-date=2024-05-28 |work=The Guardian |language=en-GB |issn=0261-3077}}</ref> During her lifetime, Hopper was awarded 40 honorary degrees from universities across the world.

== Early life and education ==
Grace Brewster Murray was born in [[New York City]]. She was the eldest of three children. Her parents, Walter Fletcher Murray and Mary Campbell Van Horne, were of [[Scottish people|Scottish]] and [[Dutch people|Dutch]] descent, and attended [[West End Collegiate Church]].<ref name="Williams">{{Cite book |last=Williams |first=Kathleen |year=2004 |title=Grace Hopper: Admiral of the Cyber Sea |url=https://books.google.com/books?id=KKmiw-_2gYIC&q=%22Grace+Hooper%22+and+military+ranks&pg=PR9 |language=en-US |location=Annapolis, MD |publisher=Naval Institute Press |isbn=978-1-61251-265-5}}</ref> Her great-grandfather, Alexander Wilson Russell, an admiral in the US Navy, fought in the [[Battle of Mobile Bay]] during the [[American Civil War|Civil War]].<ref name="Williams"/>{{rp|2–3}}

Grace was very curious as a child; this was a lifelong trait. At the age of seven, she decided to determine how an alarm clock worked and dismantled seven alarm clocks before her mother realized what she was doing (she was then limited to one clock).<ref>{{Cite journal |last1=Dickason |first1=Elizabeth |url=http://inventors.about.com/library/inventors/bl_Grace_Murray_Hopper.htm |archive-url=https://archive.today/20120712220654/http://inventors.about.com/library/inventors/bl_Grace_Murray_Hopper.htm |url-status=dead |archive-date=July 12, 2012 |title=Looking Back: Grace Murray Hopper's Younger Years |journal=Chips |date=April 1992 }}</ref> Later in life, she was known for keeping a clock that ran backward; she explained, "Humans are allergic to change. They love to say, 'We've always done it this way.' I try to fight that. That's why I have a clock on my wall that runs counterclockwise."<ref>{{Cite web |date=2021-03-29 |title=Women's History Month: Which Women Engineers Have Succeeded by Breaking the Rules? – All Together |url=https://alltogether.swe.org/2021/03/womens-history-month-which-women-engineers-have-exceeded-by-breaking-the-rules/ |access-date=2023-10-25 |language=en-US}}</ref> For her [[University-preparatory school|preparatory school]] education, she attended the [[Wardlaw-Hartridge School|Hartridge School]] in [[Plainfield, New Jersey]]. Grace was initially rejected for early admission to [[Vassar College]] at age 16 (because her test scores in Latin were too low), but she was admitted the next year. She graduated [[Phi Beta Kappa]] from Vassar in 1928 with a bachelor's degree in mathematics and physics and earned her master's degree at [[Yale University]] in 1930.

In 1930, Grace Murray married [[New York University]] professor Vincent Foster Hopper (1906–1976); they divorced in 1945.<ref name="greenladuke09">{{cite book |last1=Green |first1=Judy |author1-link=Judy Green (mathematician) |last2=LaDuke |first2=Jeanne |author2-link=Jeanne LaDuke |year=2009 |title=Pioneering Women in American Mathematics: The Pre-1940 PhD's |title-link= Pioneering Women in American Mathematics |location=Providence, RI |publisher=American Mathematical Society |isbn=978-0-8218-4376-5}} Biography on pp. 281–289 of the [https://www.ams.org/bookpages/hmath-34-PioneeringWomen.pdf Supplementary Material] at [https://www.ams.org/publications/authors/books/postpub/hmath-34 AMS]</ref><ref>{{cite news |title=Prof. Vincent Hopper of N.YU., Literature Teacher, Dead at 69 |url=https://www.nytimes.com/1976/01/21/archives/prof-vincent-hopper-of-nyu-literature-teacher-dead-at-69.html |work=The New York Times |language=en-US |date=January 21, 1976 |access-date=February 14, 2018}}</ref> She did not marry again and retained his surname.

== Career ==
=== World War II ===
[[File:Harvard Mark I sign-up.agr.jpg|thumb|Hopper's name on a duty roster for the Bureau of Ships Computation Project at Harvard, which built and operated the [[Harvard Mark I|Mark I]]]]
Hopper tried to be commissioned in the Navy early in [[World War II]], however she was turned down. At age 34, she was too old to enlist and her weight-to-height ratio was too low. She was also denied on the basis that her job as a mathematician and mathematics professor at Vassar College was valuable to the war effort.<ref>{{Cite web|url=https://www.thocp.net/biographies/hopper_grace.html|title=Grace Hopper|website=www.thocp.net|access-date=2016-12-12}}</ref> During the war in 1943, Hopper obtained a leave of absence from Vassar and was sworn into the United States Navy Reserve; she was one of many women who volunteered to serve in the [[WAVES]].{{Citation needed|date=August 2025}}

She had to get an exemption to be commissioned; she was {{convert|15|lb}} below the Navy minimum weight of {{convert|120|lb}}. She reported in December and trained at the Naval Reserve Midshipmen's School at [[Smith College]] in [[Northampton, Massachusetts]]. Hopper graduated first in her class in 1944, and was assigned to the [[Bureau of Ships]] Computation Project at [[Harvard University]] as a lieutenant, junior grade. She served on the [[Harvard Mark I|Mark I computer]] programming staff headed by [[Howard H. Aiken]].{{Citation needed|date=August 2025}}

Hopper and Aiken co-authored three papers on the Mark I, also known as the Automatic Sequence Controlled Calculator. Hopper's request to transfer to the regular Navy, out of WAVES, at the end of the war was denied due to being two years older than the cutoff age of 38. She continued to serve in the Navy Reserve. Hopper remained at the Harvard Computation Lab until 1949, turning down a full professorship at Vassar in favor of working as a research fellow under a Navy contract at Harvard.<ref name="KBW">{{cite book |last=Williams |first=Kathleen Broome |title=Improbable Warriors: Women Scientists and the U.S. Navy in World War II |year=2001 |publisher=Naval Institute Press |location=Annapolis, Maryland |isbn=978-1-55750-961-1}}</ref>

=== UNIVAC ===
In 1949, Hopper became an employee of the [[Eckert–Mauchly Computer Corporation]] as a senior mathematician and joined the team developing the [[UNIVAC I]].<ref name=Ogilvie /> Hopper also served as UNIVAC director of Automatic Programming Development for Remington Rand. The UNIVAC was the first known large-scale electronic computer to be on the market in 1951.<ref>{{Cite book |last=Camp |first=Carole Ann|date=2004 |title=American women inventors |location=Berkeley Heights, NJ |publisher=Enslow Publishers |isbn=978-0-7660-1538-8 |oclc=48398924}}</ref>

When Hopper recommended the development of a new programming language that would use entirely English words, she "was told very quickly that [she] couldn't do this because computers didn't understand English." Still, she persisted. "It's much easier for most people to write an English statement than it is to use symbols", she explained. "So I decided data processors ought to be able to write their programs in English, and the computers would translate them into machine code."<ref>{{cite web |title=Women in History |url=https://stories.vassar.edu/2017/assets/images/170706-legacy-of-grace-hopper-hopperpdf.pdf |archive-url=https://web.archive.org/web/20171006153044/http://stories.vassar.edu/2017/assets/images/170706-legacy-of-grace-hopper-hopperpdf.pdf |archive-date=October 6, 2017 |url-status=live}}</ref>

Her idea was not accepted for three years. In the meantime, she published her first paper on the subject, compilers, in 1952. In the early 1950s, the company was taken over by the [[Remington Rand]] corporation, and it was while she was working for them that her original [[compiler]] work was done. The program was known as the A compiler and its first version was [[A-0 programming language|A-0]].<ref name="mcgee2004" />{{rp|11}}

In 1952, she had an operational link-loader, which at the time was referred to as a compiler. She later said that "Nobody believed that", and that she "had a running compiler and nobody would touch it. They told me computers could only do arithmetic."<ref>{{cite web |last=Schreiber |first=Philip |date=March–April 1987 |title=The Wit and Wisdom of Grace Hopper |url=http://www.cs.yale.edu/homes/tap/Files/hopper-wit.html |website=Yale University |language=en-US |access-date=April 5, 2023}}</ref>

In 1954 Hopper was named the company's first director of automatic programming.<ref name=Ogilvie/> Beginning in 1954, Hopper's work was influenced by the [[Laning and Zierler system]], which was the first compiler to accept algebraic notation as input.<ref name="Beyer_ch10">{{cite book |last=Beyer |first=Kurt W. |year=2012 |title=Grace Hopper and the Invention of the Information Age |location=Cambridge, MA |publisher=MIT Press |isbn=9780262517263 |chapter=10}}</ref> Her department released some of the first compiler-based programming languages, including [[MATH-MATIC]] and [[FLOW-MATIC]].<ref name=Ogilvie />

Hopper said that her compiler [[A-0 System|A-0]], "translated mathematical notation into machine code. Manipulating symbols was fine for mathematicians but it was no good for data processors who were not symbol manipulators. Very few people are really symbol manipulators. If they are, they become professional mathematicians, not data processors. It's much easier for most people to write an English statement than it is to use symbols. So I decided data processors ought to be able to write their programs in English, and the computers would translate them into machine code. That was the beginning of [[COBOL]], a [[computer language]] for data processors. I could say 'Subtract income tax from pay' instead of trying to write that in octal code or using all kinds of symbols. [[COBOL]] is the major language used today in data processing."<ref>{{cite book |last=Gilbert |first=Lynn |date=1981 |title=Women of Wisdom: Grace Murray Hopper |url=https://books.apple.com/us/book/grace-murray-hopper/id1197529986 |publisher=Lynn Gilbert, Inc.}}</ref>

=== COBOL ===
[[File: Grace Hopper and UNIVAC.jpg|thumb|Hopper at the [[UNIVAC I]] console, {{Circa|1960}}]]
In the spring of 1959, computer experts from industry and government were brought together in a two-day conference known as the Conference on Data Systems Languages ([[CODASYL]]). Hopper served as a technical consultant to the committee, and many of her former employees served on the short-term committee that defined the new language [[COBOL]] (an acronym for '''CO'''mmon '''B'''usiness-'''O'''riented '''L'''anguage). The new language extended Hopper's FLOW-MATIC language with some ideas from the [[IBM]] equivalent, [[COMTRAN]].  Hopper's belief that programs should be written in a language that was close to English (rather than in [[machine code]] or in languages close to machine code, such as [[assembly language]]s) was captured in the new business language, and COBOL went on to be the most ubiquitous business language to date.<ref name="KWB">{{cite book |last=Beyer |first=Kurt W. |year=2009 |title=Grace Hopper and the Invention of the Information Age |location=Cambridge, MA |publisher=MIT Press |isbn=978-0-262-01310-9}}</ref> Among the members of the committee that worked on COBOL was [[Mount Holyoke College]] alumna [[Jean E. Sammet]].<ref>{{cite news |last=Lohr |first=Steve |date=June 4, 2017 |title=Jean Sammet, Co-Designer of a Pioneering Computer Language, Dies at 89 |url=https://www.nytimes.com/2017/06/04/technology/obituary-jean-sammet-software-designer-cobol.html |archive-url=https://ghostarchive.org/archive/20220102/https://www.nytimes.com/2017/06/04/technology/obituary-jean-sammet-software-designer-cobol.html |archive-date=2022-01-02 |url-access=limited |url-status=live |work=The New York Times |language=en-US |access-date=April 5, 2023}}{{cbignore}}</ref>

From 1967 to 1977, Hopper served as the director of the Navy Programming Languages Group in the Navy's Office of Information Systems Planning and was promoted to the rank of [[Captain (United States O-6)|captain]] in 1973. She developed validation software for COBOL and its compiler as part of a COBOL standardization program for the entire Navy.<ref name="KBW" />

=== Standards ===
In the 1970s, Hopper advocated for the Defense Department to replace large, centralized systems with networks of small, distributed computers. Any user on any computer node could access common databases on the network.<ref name="mcgee2004">{{cite book |last=McGee |first=Russell C. |year=2004 |title=My Adventure with Dwarfs: A Personal History in Mainframe Computers |url=http://www.cbi.umn.edu/hostedpublications/pdf/McGee_Book-4.2.2.pdf |archive-url=https://web.archive.org/web/20070613163123/http://www.cbi.umn.edu/hostedpublications/pdf/McGee_Book-4.2.2.pdf |archive-date=2007-06-13 |url-status=live |publisher=Charles Babbage Institute |location=University of Minnesota |access-date=May 7, 2014}}</ref>{{rp|119}} She developed the implementation of [[standardization|standards]] for testing computer systems and components, most significantly for early [[programming language]]s such as [[FORTRAN]] and COBOL. The Navy tests for conformance to these standards led to significant convergence among the programming language dialects of the major computer vendors. In the 1980s, these tests (and their official administration) were assumed by the National Bureau of Standards (NBS), known today as the [[National Institute of Standards and Technology]] (NIST).{{Citation needed|date=August 2025}}

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), and had her retirement ceremony aboard the oldest commissioned ship in the United States Navy (188 years, 9 months, 23 days).<ref>{{Cite news |work=Detroit Free Press |date=August 15, 1986 |page=4A |url=http://www.waterholes.com/~dennette/1996/hopper/860815.htm |title=Computer Whiz Retires from Navy |agency=United Press International |access-date=June 3, 2010 |archive-url=https://web.archive.org/web/20140222204821/http://www.waterholes.com/~dennette/1996/hopper/860815.htm |archive-date=February 22, 2014 |url-status=dead }}</ref>

== Post-retirement ==
After her retirement from the Navy, Hopper was hired as a senior consultant to [[Digital Equipment Corporation]] (DEC). Hopper was initially offered a position by Rita Yavinsky, but she insisted on going through the typical formal interview process. She then proposed in jest that she would be willing to accept a position which made her available on alternating Thursdays, exhibited at their museum of computing as a pioneer, in exchange for a generous salary and unlimited expense account. Instead, she was hired as a full-time Principal Corporate Consulting Engineer, a tech-track SVP-equivalent. In this position, Hopper represented the company at industry forums, serving on various industry committees, along with other obligations.<ref name="williams">{{Cite book |last=Williams |first=Kathleen |year=2004 |title=Grace Hopper: Admiral of the Cyber Sea |url=https://books.google.com/books?id=KKmiw-_2gYIC&q=%22Grace+Hooper%22+and+military+ranks&pg=PR9 |location=Annapolis, MD |publisher=Naval Institute Press |language=en-US |isbn=978-1-61251-265-5}}</ref> She retained that position until her death at age 85 in 1992.

At DEC Hopper served primarily as a goodwill ambassador. She lectured widely about the early days of computing, her career, and on efforts that computer vendors could take to make life easier for their users. She visited most of Digital's engineering facilities, where she generally received a standing ovation at the conclusion of her remarks. Although no longer a serving officer, she always wore her Navy full dress uniform to these lectures contrary to U.S. Department of Defense policy.<ref name="32CFR53.2">{{cite web |title=32 CFR § 53.2 – Policy. |url=https://www.law.cornell.edu/cfr/text/32/53.2 |website=Legal Information Institute |publisher=Cornell University |access-date=November 26, 2019}}</ref> In 2016 Hopper received the Presidential Medal of Freedom, the nation's highest civilian honor, in recognition of her remarkable contributions to the field of computer science.

"The most important thing I've accomplished, other than building the compiler," she said, "is training young people. They come to me, you know, and say, 'Do you think we can do this?' I say, 'Try it.' And I back 'em up. They need that. I keep track of them as they get older and I stir 'em up at intervals so they don't forget to take chances."<ref>{{Cite book |last=Gilbert |first=Lynn |year=2012 |title=Particular Passions: Grace Murray Hopper |edition=1st |series=Women of Wisdom Series |location=New York |publisher=Lynn Gilbert Inc. |isbn=978-1-61979-403-0}}</ref>

Throughout much of her later career, Hopper was much in demand as a speaker at various computer-related events. She was well known for her lively and irreverent speaking style, as well as a rich treasury of early war stories. She also received the nickname "Grandma COBOL".<ref>{{Cite news |url=https://www.washingtonpost.com/blogs/comic-riffs/post/grace-hopper-doodle-by-writing-computer-language-pioneering-grandma-cobol-helped-rewrite-the-history-books/2013/12/09/72a80e36-60bf-11e3-8beb-3f9a9942850f_blog.html |title=Grace Hopper: Google Doodle honors computing pioneer |last=Cavna |first=Michael |date=2013-12-09 |newspaper=[[The Washington Post]] |access-date=2018-12-07 |language=en |df=mdy-all}}</ref>

While Hopper was working on a [[Harvard Mark II|Mark II]] Computer at Harvard University in 1947,<ref name=":0" /> her associates discovered a [[moth]] that was stuck in a [[relay]] and impeding the operation of the computer. Upon extraction, the insect was affixed to a log sheet for that day with the notation, "First actual case of bug being found". While neither she nor her crew members mentioned the exact phrase, "[[debugging]]", in their log entries, the case is held as a historical instance of "debugging" a computer and Hopper is credited with popularizing the term in computing. For many decades, the term "bug" for a malfunction had been in use in several fields before being applied to [[computer bug|computers]].<ref>Edison to Puskas, November 13, 1878, Edison papers, Edison National Laboratory, U.S. National Park Service, West Orange, N.J., cited in Thomas P.

Hopper became known for her ''nanoseconds'' visual aid. People (such as generals and admirals) used to ask her why [[satellite]] communication took so long.  She started handing out pieces of wire that were just under one foot long—{{Convert|11.8|in|cm}}—the distance that light travels in one [[nanosecond]]. She gave these pieces of wire the [[Metonymy|metonym]] "nanoseconds".<ref name="DavidLetterman86">{{Cite episode | title = Late Night with David Letterman | series = Late Night with David Letterman| series-link = Late Night with David Letterman| network = [[NBC]]| location = New York City| airdate = October 2, 1986| season = 5| number = 771|quote="[to President Ronald Reagan on her promotion] Sir ...

Later she used the same pieces of wire to illustrate why computers had to be small to be fast.
