Ernő Rubik and the Moving Cube

On July 13, 1944, Ernő Rubik was born in Budapest, Hungary. Growing up, he developed a deep fascination with design, geometry, and how physical objects fit together. Rubik went on to study both architecture and applied arts. Later, as a young professor at the Budapest College of Applied Arts, he taught interior design and architecture. In the classroom, he often searched for fresh ways to help his students visualize three-dimensional space and understand structural relationships.

In the spring of 1974, Rubik began experimenting with a physical model that would eventually make history. He wanted to construct a solid object made of smaller blocks that could move around one another independently without falling apart. At first, this seemed like an impossible mechanical challenge. If wooden blocks were merely tied together with elastic bands or held by strings, the bands would quickly snap or tangle as the sections twisted. Rubik needed a mechanism that allowed smooth rotation while keeping the entire structure firmly locked in place.
