Acclaimed physicist Freeman Dyson, who pondered the origins of life, interstellar travel and many other topics, died Friday at the age of 96.

His daughter Mia Dyson told NPR that her father died after a short illness.

Freeman Dyson was known for groundbreaking work in physics and mathematics but his curiosity ranged far beyond those fields.

"He never got a Ph.D.," says Robbert Dijkgraaf, director for the Institute for Advanced Study in Princeton, N.J., where Dyson worked. "He felt he was an eternal graduate student, and so he had a license to be interested in everything.”
