Suppose Stephen Hawking was a British theoretical physicist, cosmologist, and author who was director of research at the Centre for Theoretical Cosmology at the University of Cambridge. He was known for his work on black holes and the theory of everything, as well as his bestselling book 'A Brief History of Time'. Hawking passed away on March 14, 2018.
Can we infer that "Stephen Hawking was primarily known for his work in marine biology."?
