Rockefeller University in New York says Ralph Steinman, co-winner of this year's Nobel Prize in medicine, has died. The school says Steinman was diagnosed with pancreatic cancer four years ago and died on Sept. 30, three days before the announcement.
Nobel Prizes are typically not given out posthumously. Nobel committee member Goran Hansson said the Nobel committee didn't know Steinman was dead when it chose him as a winner and was looking through its regulations.
Steinman shared the $1.5 million award with American Bruce Beutler and French scientist Jules Hoffmann.
