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

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 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.

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 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."

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

The inaugural recipient of the award—symbolic of the male-dominated nature of computer science—was honored in 1969 for her contributions to the development of COBOL and the first compiler. Hopper would also become the first woman from any country and the first American to be recognized as a Distinguished Fellow of the British Computer Society.

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."

The Grace Hopper Celebration honors women in computing every year

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.

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.

At the age of seven, Grace Hopper dismantled alarm clocks

Foreshadowing a career in computers, Hopper exhibited a curiosity for gadgets at a young age and took apart seven clocks, determined to understand how they worked. Despite having a dollhouse, Hopper built an elevator for it and showed a greater interest in building toy furniture than playing with dolls.

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.)

The history of the commercialization of the internet, from ARPANET to NSFNET and beyond

NSFNET was launched in 1986 by the National Science Foundation as the first network available to all researchers, connecting them to a system of supercomputer facilities. Despite growing from 2,000 computers in 1985 to 2 million by 1993, the rapid expansion of commercial internet services led to NSFNET's decommissioning by 1995.

Long after his death, Washington was made the highest-ranking military figure in US history

Only three Americans have held the rank of General of the Armies: John J. Pershing, Ulysses S. Grant, and Washington. However, Washington still outranks the others because Congress passed a 1976 law stating that he outranks all officers "past or present."

'It might be that some day I shall be drowned by the sea, or die of pneumonia from sleeping out at night, or be robbed and strangled by strangers. These things happen. Even so, I shall be ahead because of trusting the beach, the night and strangers.'
