Famous Females: Ada Lovelace

Inventors tend to think like this. They might see a wheel and invent a bicycle, or a bird and invent a plane. Ada Lovelace saw a calculator and imagined a computer!

Think of the difference between a calculator and a computer. A calculator is useful, sure – especially in math class! But also if you’re building something like a skyscraper, doubling a recipe for baking cakes, shopping at the grocery store, or trying to get a rocket  launched into space.

A basic calculator is great for short-cutting math problems, but it doesn’t play music, show videos, or let you draw pictures.

Ada Lovelace imagined and understood a world of computers that was over a century ahead of her time. Let’s learn more about this famous female of computer programming.

ADA LOVELACE (Augusta Ada Byron) (1815-1852)

ada lovelaceAda Lovelace was born in London, the child of Lord Byron, a famous Romantic poet. However, his marriage to Ada’s mother Annabella was quick and unhappy. They separated a month after Ada’s birth, and Ada would never meet him.

Determined her daughter would not inherit her father’s mood swings and erratic behavior, Annabella immersed Ada in education by the age of four. Particularly subjects that were full of logic, like mathematics. One of her tutors was Mary Somerville, an astronomer!

By the time she was 12, Ada was fascinated with the idea of making a flying apparatus, and toyed with ideas of powered flight.

Ada went to his house the next day and was able to see the thing in person. She was hooked. From then on, she and Babbage wrote letters to each other until her death at age 36.

But Babbage was already working on another, better machine before he finished the first one. He called it the ‘Analytical Engine’, and this one could do even more difficult calculations.

He asked an Italian engineer to write an article about it, and enlisted Lovelace to translate it from French to English.

It was published in 1843, and she only initialed it with A.A.L., for her birth name (the name we know now comes from her marriage).

Within these Notes is the very first computer program. She explained (in Note G) the sequence of operations for how a code could be written so the machine could calculate Bernoulli numbers.

Lovelace also mentioned that there was no reason the machine couldn’t also read codes for letters and symbols too, in addition to just numbers. She talked about how it should be able to repeat a series of instructions – something we know as ‘looping’, used in programming today.

Wait, a machine that could do something other than represent quantities? This was unheard of. Lovelace had just quietly invented the concept of computing.

She said that “the science of operations, as derived from mathematics more especially, is a science of itself, and has its own abstract truth and value.” By 'science of itself' she unwittingly refers to computer science!

She figured that sound, music, text, and pictures could made digital and even manipulated by engines such as these. This was going way beyond just the numbers.

It was only about a century later that a book called “Faster Than Thought: A Symposium on Digital Computing Machines” would bring them back into the limelight. This was in 1953, when computer science was just beginning to be explored.

In the ‘70s, the US Department of Defense made a new programming language.  A Navy Commander suggested naming it ‘Ada’ in tribute. ‘Ada’ is still used today in everything from space research, to transportation, to healthcare.

So, what do you imagine? Who knows where it could lead!
