Grace Hopper won the Data Processing Management Association's 'Man of the Year' award

Grace Hopper was named the 1959 Time magazine 'Woman of the Year'

The honor was part of the 2019 series "100 Women of the Year," which spotlighted an influential woman for each of the years the publication had previously awarded a "Man of the Year." In its write-up, Hopper was described as having "paved the way for women everywhere to thrive in math, computer science, and service to their countries."

For her contributions, Grace Hopper received more than 40 honorary degrees

Beyond the scholarships, professorships, and awards named in her honor, President George Bush awarded Hopper the National Medal of Technology in 1991 for her work in developing computer programming languages that enhanced accessibility. In 1996, Hopper became only the second woman to have a US Navy warship named after her.

Grace Hopper described serving in the US Navy as the highest award she received

Despite retiring from the US Naval Reserve in 1966 at 60, as stipulated by Navy regulations, Hopper was repeatedly recalled for her pioneering expertise in computer science. By 1983, three years before her final retirement, she would give lectures about 200 days a year to computer scientists at military bases, college campuses, and businesses on behalf of the Navy.

The Grace Hopper Celebration honors women in computing every year

Since 1994, the world's largest gathering of women technologists has been produced by The Anita Borg Institute, a nonprofit driving intersectional equity in the global technical workforce. The event honors the legacy of Grace Hopper by highlighting the research and impact of women in technology.

Grace Hopper was inspired to join the armed forces after the attack on Pearl Harbor

Despite being too old to enlist and weighing below the required minimum to serve, Hopper was granted an exemption and assigned to work on the first electromechanical computer produced in the US. She and her team spent three months using the device to solve equations needed to design the implosion mechanism for the atomic bomb.

Grace Hopper graduated first in her class of 800 officer candidates

As a volunteer in the Women Accepted for Volunteer Emergency Service program, Hopper was able to fulfill roles beyond the nursing and clerical responsibilities normally available to women in the military. However, once World War II concluded and the emergency status was lifted, the Navy declined her request for a regular commission.

President Barack Obama compared Grace Hopper to the Wright Brothers

When posthumously awarding Hopper with the Presidential Medal of Freedom—the nation's highest civilian honor—on Nov. 22, 2016, the former president remarked, "If Wright is flight, and Edison is light, then Hopper is code. [...] From cell phones to [US] Cyber Command, we can thank Grace Hopper for opening programming to millions more people."

Grace Hopper warned against prioritizing hardware purchases in future computing

Foreseeing the rising volume of data and the increasing demand for its processing and access, she advocated that organizations first map the total flow of information they require and then choose infrastructure to support it, rather than wastefully spending on the fastest computing technology and forcing software to compensate for unnecessary hardware or incorrect data.

In 2017, Yale renamed one of its colleges to honor Grace Hopper

Founded in 1933, the Calhoun College—one of Yale's 12 undergraduate residential colleges—was renamed to Grace Hopper College in honor of the woman who earned a master's degree and PhD in mathematics from the university in the 1930s. The change was also made to distance the school from white supremacist John C. Calhoun.

The first compiler to facilitate communication with computers was developed by Grace Hopper

The A-0 program linker automatically translated mathematical symbols into machine-readable binary code. Although it took two years for computer executives to get on board with the idea, the technology was foundational to future programming languages that allowed computers to understand commands written in word-based languages.

Later in life, the clock in Grace Hopper's office ran counterclockwise

Acknowledging that most people have "an enormous tendency to resist change," Hopper's clock served as a reminder for the computer scientist that just because things have been done a certain way does not mean they should forever remain that way: "They love to say, 'We've always done it this way.' I try to fight that." (Some users may experience a paywall.)

NVIDIA named several computer chip architectures after Grace Hopper

Unveiled in 2023, the GH200 Grace Hopper Superchip, designed for generative AI applications in data center-scale systems, combines a Grace CPU with a Hopper GPU to create a coherent memory model. This allows the Hopper to access Grace data directly, reducing the need to repeatedly copy data back and forth and vastly improving performance.

COBOL was partly derived from Grace Hopper's FLOW-MATIC programming language

The Common Business-Oriented Language was developed for business data processing, supporting precise decimal calculations and an English-like syntax. Able to work across operating systems and hardware environments, COBOL and its newer versions support 80% of in-person credit card transactions and 95% of all ATM transactions.

Computer pioneer Alan Turing was also an elite runner

Alan Turing is credited with helping to found modern computer science, in addition to cracking the Nazi code known as Enigma. Beyond these world-historical achievements, the British mathematician also nearly represented his country in the Olympics in the marathon, running just 11 minutes slower than the eventual gold recipient at the 1948 games. Read more on this lesser-known aspect of the man here.

English mathematician Ada Lovelace wrote the first computer algorithm a century before computers existed and hypothesized that computing devices would one day be able to compose music—foreseeing the generative AI systems of today.

Women were barred from MBA enrollment for half a century

In 1908, Harvard launched the first modern MBA—and only admitted male candidates. The first full-year traditional female MBA students wouldn’t enroll at Harvard until 1963. Learn more about the history of the first women to receive their MBAs on Harvard’s website.

Kathrine Switzer was the first official female finisher in the Boston Marathon

A year after Bobbi Gibb’s unofficial finish, Kathrine Switzer registered under an androgynous name to avoid suspicion. Race officials unsuccessfully tried to remove her from the race while she was competing (pictured below), but she ultimately became the first woman to officially finish the race. In 1972, the Boston Marathon changed its rules to allow women to register.

Sylvia Robinson is considered ‘the Godmother of Hip-Hop’

While hip-hop was soundtracking countless parties in the early ‘70s, Robinson saw the music’s potential. She began writing, producing, and releasing some of the music’s earliest singles through her Sugar Hill Records label and helped build a place in the music industry for the young music. Robinson’s groundbreaking work led to a 2022 induction into the Rock and Roll Hall of Fame.
