Ada Lovelace was born on 10 December, 1815. Now 205 years on, it’s hard to underestimate the remarkable impact her work has had upon our world.

If you look up a history of programming, Ada Lovelace is recognized as where it begins. Her widely acknowledged role as the world’s first computer programmer places her alongside influential figures such as Charles Babbage, George Boole, and Alan Turing in the formative journey of computing technologies. It’s difficult to contemplate where contemporary icons such as Sir Tim Berners-Lee, Bill Gates, and Steve jobs might be without these legendary foundations. 

Ada Lovelace’s remarkable journey began as a daughter to two remarkable parents. Her father was the infamous Lord Byron, famous 19th century British poet and politician. Her mother, Lady Anne Isabella Noel Byron,  was a renowned mathematician in her own right. When her parents separated, it was her mother’s influence and schooling in philosophy, science, and mathematics that inspired Ada’s own journey.

Ada Lovelace remains an inspiration to programmers around the world. Her legacy frames a particular focus on the important role of women in science, technology, engineering, and mathematics (STEM) roles, and one which is now celebrated annually on Ada Lovelace Day.

Neural Technologies’ own capabilities in advanced machine learning and artificial intelligence solutions are built on the backs of astonishing figures like Ada Lovelace. On the 205th anniversary of her birth, that provides a remarkable opportunity to celebrate her accomplishments. 

The Analytical Engine

Ada’s marriage at the age of 19 to one William King ultimately led to becoming Lady Ada King, Countess of Lovelace. Yet it was her encounter with visionary inventor Charles Babbage in 1833 that defined her legacy.

Babbage had dreamt of designing a mathematical device which could undertake complex computations. His so-called Analytical Engine was a descendant of his early Difference Engine concept. But while the Difference Engine could complete simple calculations, the Analytical Engine was envisioned as undertaking far more sophisticated computational tasks. 

The Analytical Engine echoed many of the familiar elements of computing devices we recognize today. It was programmable through a simple punch card system. It included a ‘memory’ for numbers and results to be stored, and a ‘mill’ where processing was performed. These critical elements of functionality remain remarkably consistent with the more complex systems Neural Technologies now works with.

Ada Lovelace was fascinated by Babbage’s work. She studied the designs and research on the Analytical Engine in great detail, exploring how such a system might work in practice. In 1843 she published a translation of a French article on Babbage’s work by Italian engineer Luigi Menabrea, in which she commented that the device “might act upon other things besides numbers… the Engine might compose elaborate and scientific pieces of music of any degree of complexity or extent.”

Her investigations into Babbage’s work went further to describe how codes could be employed to program the machine, taking those important steps towards that legacy as the world’s first programmer.

These investigations included a method that would enable the Analytical Engine to repeat a series of preprogrammed instructions. This functionality known as ‘looping’ is still employed in computer systems today, repeating instructions until a particular desired condition is met.

Ada’s remarkable legacy

Such was the value of Ada Lovelace’s work, it was published in an English science journal in 1843. That reflects a remarkable achievement at a time when women were largely excluded from academic circles. 

Lovelace sadly died at the age of just 32, with her work largely being forgotten in the century to come. It was only in the 1940s that Alan Turing, the father of modern computing, discovered her work and used it as inspiration for his own work in the development of contemporary computing technology. 

It’s fascinating to think what Ada Lovelace would make of modern computing systems. The advanced capabilities of Neural Technologies’ Optimus platform are far removed from the pioneering vision of the Analytical Engine. Integrating billions of data points in real-time is the result of a technical evolution that would perhaps be unthinkable to those 19th century visionaries. Equally remarkable however is how fundamental similarities with those early machines remain.

Over two centuries on, Ada Lovelace’s legacy as the first computer programmer is firmly established. In 1980, the Ada programming language was even named in her honour. But her true legacy, as with those that followed in her footsteps, remains the capabilities and opportunities of our remarkable modern computing landscape.
