Stephen Hawking’s Early Life

Stephen William Hawking was born on January 8, 1942, in Oxford, England—coincidentally 300 years to the day after Galileo’s death. From a young age, Hawking showed a remarkable aptitude for mathematics and science. Despite average grades early on, he won a scholarship to Oxford University, where he earned a degree in physics, and later completed his PhD at the University of Cambridge.

At just 21, Hawking was diagnosed with amyotrophic lateral sclerosis (ALS), a neurodegenerative disease. Doctors gave him only a few years to live. Instead, he defied all expectations and lived for more than five decades, becoming a global symbol of resilience and genius.
