Amos Tversky

Israeli-American psychologist and cognitive scientist — co-creator with Kahneman of prospect theory and the heuristics-and-biases research program — the most brilliant of the behavioral economics founders — who died of cancer at 59 before the Nobel was awarded.

Co-creates the empirical foundation of behavioral economics — Tversky's combination of rigorous experimental design, mathematical precision, and psychological insight produced the heuristics-and-biases program with Kahneman; his early death before the Nobel meant the prize went solely to Kahneman.
