Psychologist and bestselling author Daniel Kahneman, whose research on how decision-making and biases can impact economics earned him a Nobel Prize, died on March 27. He was 90.

Kahneman was born in Tel Aviv, Israel, on March 5, 1934, and was raised in Paris until his family fled Nazi-occupied France. He graduated from Hebrew University in 1954 and received a doctorate in psychology from the University of California, Berkeley, in 1961. In 1993, he joined the faculty of Princeton University, where he spent much of his career. He went on to receive the Nobel Memorial Prize in Economic Sciences in 2002 and the Presidential Medal of Freedom in 2013.
