Mathematician and theoretical physicist. Since 1979 Hawking has been Lucasian Professor of Mathematics at Cambridge University, a post famously held by Sir Isaac Newton. His early research on relativity led him to study the Big Bang, the creation of the universe and black holes. He has a progressive neuromotor disease, amyotrophic lateral sclerosis (ALS). He uses a wheelchair and speaks through an electronic voice synthesizer. Hawking continues to work and has produced several best-selling books including A Brief History of Time (1988), Black Holes and Baby Universes (1993) and The Universe in a Nutshell (2001). His life is the subject of a 2014 film, The Theory of Everything.
