Ada Lovelace
1815–1852 · Mathematician
Often called the world's first computer programmer, Ada Lovelace envisioned that computers could do far more than calculate numbers.
“That brain of mine is something more than merely mortal; as time will show.”
Ada wrote the world's first computer program in 1843 — nearly a century before the first electronic computer was built.
Why is this scientist famous?
Writing the first computer algorithm, a century before electronic computers existed.
Every time you play a video game, use an app, or ask a smart speaker a question, you are using code — the kind of step-by-step instructions Ada Lovelace imagined nearly 200 years ago. She proved that machines could do more than just calculate: they could create music, art, and ideas. That idea is the heartbeat of every computer and phone in your pocket today.
Ada's story
Early Life
Born Augusta Ada Byron, daughter of the famous poet Lord Byron. Her mother, Annabella Milbanke, separated from Byron when Ada was five weeks old and deliberately steered her daughter toward mathematics and logic, hoping to suppress any inherited poetic tendencies.
Meeting Babbage
At age 17, Ada met Charles Babbage, who showed her his "Difference Engine" — a mechanical calculator. She was captivated. Babbage later designed the "Analytical Engine," a far more ambitious machine that could, in principle, perform any calculation — a true general-purpose computer.
The First Algorithm
In 1843, Ada translated an Italian article about the Analytical Engine and added her own extensive notes. Her "Note G" described a step-by-step method for calculating Bernoulli numbers — the first published algorithm intended for a machine to execute. She also predicted that such a machine could compose music and produce graphics, not just crunch numbers.
Legacy
Ada died of uterine cancer at just 36, her brilliance cut short. Over a century later, the U.S. Department of Defense named its programming language "Ada" in her honour, and she has become a powerful symbol for women in technology.
What did they discover?
First Computer Algorithm
Wrote a detailed method for the Analytical Engine to compute Bernoulli numbers — the first algorithm designed for a machine.
Vision of General-Purpose Computing
Foreseeing that computers could manipulate any symbol — music, text, images — not just numbers, she described what we now call general-purpose computing.
Amazing facts
She was the daughter of the famous poet Lord Byron, whom she never knew.
Her mother pushed her toward mathematics specifically to prevent her from developing her father's "dangerous" poetic temperament.
She predicted that computers could one day compose music and graphics — in 1843.
The Ada programming language, created by the U.S. military, is named after her.
Ada Day, held each October, celebrates the contributions of women in STEM.
She died at only 36, the same age as her father.
