Stephen Hawking
Hawking's work centered around the study of black holes, the origins of the universe, and the fundamental laws of physics. He proposed that black holes emit radiation, now known as Hawking radiation, which led to a better understanding of the behavior of these enigmatic objects. His work on the nature of time and space also helped to reconcile quantum mechanics and general relativity, two of the most important theories in physics.
Despite being diagnosed with motor neuron disease at the age of 21, which eventually left him paralyzed, Hawking continued to pursue his research and became a public figure, known for his popular science books and his ability to communicate complex ideas to a broad audience. He was a professor at the University of Cambridge and held numerous awards and honors throughout his career, including the Albert Einstein Medal and the Presidential Medal of Freedom.
