I. Early Life and Education: Building the Foundation (The Shipyard!)
Grace Brewster Murray was born in New York City on December 9, 1906. And right from the start, she was… curious. Seriously curious. Think "kid dismantling the alarm clock to see how it works" kind of curious. 🕰️ Apparently, at the age of seven, she disassembled seven alarm clocks to find out how they worked. Let’s just say her mother wasn’t thrilled, but that inherent curiosity was the spark that would ignite her incredible career.
She had a thirst for knowledge that could rival the Sahara Desert. She wasn’t content with just accepting things as they were; she wanted to understand the why and the how behind everything.
(Professor gestures dramatically.)
Grace’s parents, thankfully, recognized and nurtured this insatiable curiosity. They encouraged her intellectual pursuits and provided her with access to quality education.
- Vassar College (1928): Bachelor’s degree in Mathematics and Physics. 🎓
- Yale University (1930): Master’s degree in Mathematics. 📚
- Yale University (1934): Ph.D. in Mathematics (One of the first women to earn a Ph.D. in Math from Yale!). 👩🎓
Her doctoral dissertation, titled "New Types of Reduction Criteria," was a testament to her intellectual prowess and demonstrated her deep understanding of abstract mathematical concepts.
(Professor points to a table on the slide.)
Here’s a quick summary of her academic journey:
| Institution | Degree | Year |
|---|---|---|
| Vassar College | Bachelor of Arts (Mathematics/Physics) | 1928 |
| Yale University | Master of Arts (Mathematics) | 1930 |
| Yale University | Doctor of Philosophy (Mathematics) | 1934 |

II. Naval Service: From Mathematics to Computing (Setting Sail!)
Now, you might be thinking, "Okay, she’s a brilliant mathematician. What does that have to do with computers?" Well, buckle up, because this is where things get interesting!
World War II was raging, and Grace, ever the patriot, felt compelled to contribute to the war effort. Despite being initially rejected due to her age and weight, she persisted and eventually secured a commission in the U.S. Naval Reserve in 1943. ⚓️
(Professor adopts a slightly more serious tone.)
This was a pivotal moment in her life. She was assigned to the Bureau of Ordnance Computation Project at Harvard University, where she joined the team working on the Harvard Mark I, one of the first electromechanical computers.
Imagine stepping into a room filled with wires, relays, and gears, all whirring and clicking away. This was the world of early computing. It wasn’t sleek and streamlined like our smartphones; it was a massive, complex machine that filled an entire room!
(Professor clicks to a picture of the Harvard Mark I.)
The Mark I was used to perform complex calculations for the war effort, such as calculating ballistics tables. Grace’s mathematical background proved invaluable in this environment. She quickly learned the intricacies of the machine and became a skilled programmer. She wasn’t just crunching numbers; she was teaching the machine how to crunch them.
(Professor adds a touch of humor.)
Legend has it that she even coined the term "computer bug" when a moth got stuck in one of the Mark II’s relays, causing a malfunction. 🐛 She taped the moth into the logbook with the note: "First actual case of bug being found." True or not, it’s a great story!
(Professor clicks to the next slide: III. The Mark I and Beyond: Early Computing Pioneers (Charting the Course!))

After the war, Grace continued her work in computing. She remained at Harvard as a research fellow and worked on the Mark II and Mark III computers. This period was crucial in shaping her vision for the future of computing.
(Professor emphasizes the next point.)
She realized that computers were more than just giant calculators. They had the potential to be powerful tools for solving a wide range of problems, but only if they could be made more accessible and easier to use.
In 1949, she joined the Eckert-Mauchly Computer Corporation, which later became the Remington Rand Corporation. This was a significant move because it put her at the forefront of commercial computing.
At Remington Rand, she worked on the UNIVAC I, the first commercially available electronic digital computer. This was a game-changer! Suddenly, businesses and organizations could harness the power of computers to automate tasks, analyze data, and improve efficiency.
(Professor pauses for effect.)
But Grace wasn’t content with just building and selling computers. She wanted to make them easier to program. She envisioned a world where programmers could write code in a language that resembled English, rather than having to deal with complex machine code.

This brings us to one of Grace Hopper’s most significant contributions to computer science: the compiler.
(Professor explains with passion.)
In the early days of computing, programming was a tedious and error-prone process. Programmers had to write code in machine language, which consisted of long strings of binary numbers (0s and 1s). It was like trying to build a house using only individual atoms!
Grace realized that this was a major barrier to wider adoption of computers. She believed that programming should be more intuitive and accessible, allowing programmers to focus on the logic of their programs rather than the intricacies of machine code.
(Professor uses an analogy.)
Think of a compiler like a translator. You write your instructions in a language you understand (like English), and the compiler translates those instructions into a language the computer understands (machine code). Suddenly, programming becomes much easier and more efficient! 🗣️➡️💻
In 1952, Grace and her team developed the A-0 System, one of the first compilers. This was a revolutionary breakthrough! It allowed programmers to write code in a symbolic language, which was then translated into machine code by the compiler.
(Professor highlights the impact.)
The A-0 System paved the way for the development of more sophisticated compilers and programming languages, ultimately transforming the way we interact with computers.
(Professor clicks to the next slide: V. COBOL: A Common Business Language (Building Bridges!))
V. COBOL: A Common Business Language (Building Bridges!))
Building on her work with compilers, Grace Hopper played a key role in the development of COBOL (Common Business-Oriented Language).
(Professor emphasizes the importance of COBOL.)
COBOL was designed to be a standardized programming language that could be used across different computer systems. This was crucial for businesses that wanted to develop applications that could run on multiple platforms.
Grace believed that COBOL should be based on English-like syntax, making it easier for non-technical people to understand and use. She famously said, "I thought, wouldn’t it be nice if we could write programs in English? So I decided to try to do it."
(Professor quotes Grace Hopper with enthusiasm.)
COBOL quickly became the dominant programming language for business applications. It was used to develop systems for banking, finance, insurance, and many other industries.
(Professor shares a statistic.)
Even today, decades after its creation, COBOL is still used in many mission-critical systems around the world. It’s estimated that COBOL powers trillions of dollars in transactions every day! 🤯
While newer languages have emerged, COBOL’s enduring legacy is a testament to Grace Hopper’s vision and her commitment to making programming more accessible.

Grace Hopper was not only a brilliant scientist but also a fantastic communicator. She had a knack for explaining complex concepts in a way that everyone could understand.
(Professor introduces the concept of the nanosecond.)
One of her most famous demonstrations involved the concept of a nanosecond, which is one billionth of a second. This is an incredibly short amount of time, and it can be difficult to grasp.
To illustrate the speed of a nanosecond, Grace would hand out pieces of wire that were approximately 11.8 inches long. She explained that this was the distance that electricity could travel in one nanosecond.
(Professor demonstrates with an imaginary piece of wire.)
"This," she would say, holding up the wire, "is a nanosecond. It’s the distance that electricity travels in one billionth of a second. Now, when you’re talking about computers, this is important!"
This simple demonstration helped people understand the incredible speed at which computers operate. It also highlighted the importance of optimizing code to minimize the distance that electricity has to travel. ⚡

(Professor shares a personal reflection.)
But perhaps her greatest legacy is the impact she had on the lives of countless individuals who were inspired by her passion and dedication. She showed us that anything is possible with hard work, creativity, and a willingness to challenge the status quo.
(Professor quotes Grace Hopper again.)
"Dare and do," she often said. "You’ll be surprised at what you can accomplish."
