Marvin Minsky, a pioneer in the field of artificial intelligence who saw parallels in the functioning of the human brain and computers, has died aged 88.
Mr Minsky died at Brigham and Women's Hospital in Boston of a cerebral haemorrhage, the Massachusetts Institute of Technology (MIT) said.
The scientist viewed the brain as a machine whose functioning can be studied and replicated in a computer and considered how machines might be endowed with common sense.
He "helped create the vision of artificial intelligence as we know it today", said Daniela Rus, director of MIT's computer science and artificial intelligence laboratory.
Mr Minsky served in the US navy during the Second World War before earning mathematics degrees from Harvard and Princeton. He joined MIT's faculty in 1958.
He is survived by his wife and three children.
