Consider a world where art isn’t just created by human hands but by lines of code and complex algorithms. This isn’t science fiction – it’s the world of AI art, and its origins can be traced back to a visionary artist named Harold Cohen.

A Traditional Artist with a Technological Vision

Harold Cohen wasn’t your typical computer programmer. Born in 1923, he established himself as a successful British artist known for his bold and expressive ink drawings. However, Cohen wasn’t content with just traditional methods. He was fascinated by the potential of computers and their ability to create new forms of expression.

In the late 1960s, while a visiting professor at the University of California, San Diego, Cohen encountered the burgeoning field of artificial intelligence (AI). He saw a unique opportunity – to use computers not just as tools for creating art, but as artistic collaborators capable of independent thought and expression.

AARON: Birth of a Digital Artist

Cohen’s vision materialized in the form of AARON, a groundbreaking computer program he began developing in 1968. AARON wasn’t simply a program that generated random images. It was a complex system designed to learn and grow over time.

Harold Cohen’s genius with AARON wasn’t simply creating a program that could draw lines. He envisioned a system with a built-in artistic vocabulary and the ability to learn and evolve. This was achieved through a complex set of procedural rules. Imagine these rules as a set of instructions for AARON, a digital artist with a virtual paintbrush and an ever-growing artistic toolbox.

These procedural rules weren’t static commands like “draw a line from point A to point B.” Instead, they were more like artistic principles that defined AARON’s creative process. Here’s a deeper dive into how these rules functioned:

Movement Rules: 

These rules dictated how AARON would move its virtual pen across the canvas. They might specify the direction of movement (straight lines, curved lines, zig-zags), the length of strokes, or even the pressure applied (think thin lines vs. thick strokes).

Mark-Making Rules: 

Beyond simple lines, AARON could be instructed to create more complex marks. Imagine rules for creating dots, dashes, splatters, or even geometric shapes. These rules could be combined to create a diverse range of textures and effects.

Compositional Rules: 

AARON wasn’t just drawing random lines. Procedural rules could govern the overall composition of the artwork. These rules might define how elements were arranged on the canvas, the use of negative space, or even the density of marks in different areas.

Learning from Experience: The Key to AARON’s Evolution

But Cohen’s vision didn’t stop at a set of pre-programmed rules. A crucial aspect of AARON was its ability to learn and evolve. Here’s how this learning process worked:


After generating an artwork, AARON would analyze its creation based on the pre-defined rules. This analysis could consider factors like the overall composition, the balance of elements, or the effectiveness of different mark-making techniques.

Rule Refinement: 

Based on the evaluation, AARON could adjust its procedural rules. It might increase the use of successful techniques, decrease the use of less successful ones, or even introduce new rules entirely.

Evolving Style: 

Through this ongoing process of analysis and refinement, AARON’s artistic style would gradually evolve. Over time, the program would develop its unique preferences and tendencies, leading to a diverse and ever-changing artistic output.

This ability to learn and adapt is what truly sets AARON apart from other early attempts at computer-generated art. It wasn’t just a static program following a script; it was a dynamic artistic entity constantly refining its creative approach.

AARON’s creations demonstrated a remarkable level of sophistication. The program wasn’t simply mimicking existing art forms; it was creating entirely new visual languages. You can find examples of AARON’s work on the Cohen website

The Impact of Harold Cohen and AARON

Harold Cohen’s pioneering work with AARON had a profound impact on the art world. It challenged traditional notions of artistic creation and opened up exciting new possibilities for the future of art. Here’s how:

Harold Cohen’s work with AARON wasn’t just a single artistic project; it was the spark that ignited the entire field of AI art.  Here’s why his contribution is considered so foundational:

From Predetermined Images to Artistic Exploration: Before AARON, computer-generated art often consisted of geometric patterns or simple visualizations of mathematical algorithms. Cohen’s approach revolutionized this. AARON wasn’t programmed to create specific images; it was designed to explore the act of artistic creation itself. This shift in focus opened up a whole new realm of artistic possibilities using AI.

A Bridge Between Human and Machine Creativity:  AARON served as a bridge between the worlds of human artistry and computer programming. Cohen, an established painter himself, imbued AARON with a set of artistic principles. These principles, translated into the language of code, allowed the program to generate art that wasn’t just technical but also possessed a sense of balance, composition, and even a touch of serendipity.

Inspiring a Generation:  

Cohen’s work wasn’t just a one-off experiment. It captured the imagination of artists and programmers alike. His exploration of AI art sparked a movement. Artists saw the potential of AI as a tool to expand their creative horizons, while programmers were inspired to create new AI systems for artistic expression.

AARON’s Art: Blurring the Lines of Authorship

The ability of AARON to create independent artwork raised a fundamental question: who is the artist?

  • The Programmer as the Architect:  There’s a strong argument to be made that the artist is Harold Cohen, the programmer who meticulously crafted the rules that governed AARON’s actions.  He was the architect who built the artistic framework, defining the tools and parameters within which AARON could operate.
  • The Program as the Creative Mind:  On the other hand, AARON wasn’t simply following a pre-defined script.  Through its learning and evolution, the program displayed a level of independent creativity.  The specific choices it made in mark-making, composition, and overall style were not pre-programmed but emerged from its internal processes. This raises the question of whether AARON itself possessed a degree of artistic agency.
  • A Collaborative Endeavor:  Perhaps the most interesting perspective is to see AARON’s art as a product of collaboration. Cohen created the framework, but it was AARON’s interaction with those rules and its internal learning mechanisms that produced the final artwork.  This collaborative approach continues to be explored by artists today who use AI tools alongside their creativity.

The debate about authorship in AI art remains ongoing, and there’s no single definitive answer. However, Cohen’s work with AARON forced us to re-evaluate our understanding of artistic creation in the digital age.  It opened up a conversation about the potential for machines to be not just tools, but collaborators in the artistic process.
