Nobel prize winning mathematician, John Nash was killed in a car accident on May 24 along with his wife. The 86-year-old had had a flourishing career, for which he was honoured with a Nobel prize and an Abel prize – one of the most prestigious honours in mathematics.

He was also the subject of the award-winning film A Beautiful Mind , which depicted his groundbreaking work in game theory. Game theory offers insight into the dynamic of conflict and human rivalry, and is often considered one of the most influential ideas of the 20th century.

The film also shows Nash’s struggles with mental illness. John Nash suffered from schizophrenia, and later in life became an advocate for mental health awareness and improving mental health care.

Nash was associated with Princeton University for many years, most recently serving as a senior research mathematician.

A number of people from around the world have flocked to Twitter to share their grief, including economists, politicians, actors and others who held him in high regard.
