When and where Stephen Hawking died
Stephen Hawking died on 14 March 2018 at his home in Cambridge, England. He was 76. His family publicly announced his death shortly afterward, noting he died peacefully.
Cause of death
Hawking had been living with amyotrophic lateral sclerosis (ALS), a progressive neurodegenerative disease. While ALS was noted on his death certificate, reports from his family and physicians emphasized that he died peacefully at home, consistent with his long-term condition.
Stephen Hawking: profile breakdown
Hawking was a theoretical physicist, cosmologist, and author whose work on black holes, cosmology, and quantum gravity shaped modern physics. Despite a progressive diagnosis in his early twenties, he continued research, public communication, and advocacy for decades.

Scientific legacy and contributions
Hawking’s research on singularities, event horizons, and thermal radiation from black holes remains foundational. Collaborations with mathematicians and physicists extended general relativity into quantum regimes, influencing debates on information, entropy, and the nature of time.
Notable concepts associated with Hawking
- Hawking radiation: theoretical emission from black holes due to quantum effects near the event horizon.
- No-boundary proposal: model suggesting the universe has no initial boundary in imaginary time.
- Singularity theorems: conditions under which spacetime singularities must form.
- Popular science communication: books including A Brief History of Time.
Public communication and cultural impact
Hawking made theoretical physics accessible to millions through lectures, documentaries, and best-selling books. His presence in popular culture did not diminish his scientific rigor; he consistently clarified that his work addressed profound questions about the universe, not philosophical speculation about meaning.
Health and ALS context
ALS progressively impairs motor neurons, leading to loss of muscle control. Hawking used a wheelchair and later a speech-generating device, yet continued research and public engagement for many decades. His longevity with ALS is rare, and clinicians noted both the extraordinary nature of his case and the relentless course of the disease.
Reactions and tributes
Colleagues, institutions, and the public widely acknowledged his intellect, resilience, and clarity of thought. Tributes highlighted his ability to connect deep ideas with everyday curiosity, while underscoring the importance of evidence-based science in public discourse.
What to remember
Stephen Hawking died on 14 March 2018 at age 76 at his home in Cambridge. The cause was linked to complications from ALS, but he died peacefully at home surrounded by family. His scientific work on black holes, cosmology, and quantum gravity remains influential, and his writings continue to reach broad audiences.
