One of the world’s most notable living scientists Stephen Hawking turned 72 years old today (January 8th). He was given two years to live in 1963, but has despite of that revolutionized physics for the next half of a century.

“My goal is simple. It is a complete understanding of the universe, why it is as it is and why it exists at all.”

These images above were captured by Howard Grey in 1963 when Stephen was 22 years old.
