William Vickrey died three days after his 1996 Nobel Prize in Economic Sciences was announced, fitting the Foundation's post-1974 posthumous exception

William Vickrey, awarded the 1996 Nobel Prize in Economic Sciences for work on the economics of incentives under asymmetric information, died on 11 October 1996 in Harrison, NY — three days after the Nobel committee announced the award. The Foundation's own laureate-facts page records it directly: "Vickrey passed away on October 11th, 1996, only three days after the announcement of his Economic Sciences Prize."

Combined with the Foundation's 1974 statute revision, which permits a posthumous award only when death occurs after the announcement but before the December ceremony, Vickrey's case is the Foundation's own confirmation that his award falls inside that post-1974 exception window. It is a distinct mechanism from Ralph Steinman's 2011 case, where the committee's decision itself predated news of his death rather than following an announcement he lived three days past.

[unverified-quant — needs primary] No other case of a Nobel laureate dying between announcement and ceremony after 1974 turned up in this session's research besides Vickrey's. That absence is a search-engine result, not a check against Nobel Foundation records, so this note records Vickrey as the clearest documented case fitting the clause rather than as a verified "sole" case — the completeness question stays open but is not load-bearing to the claim above.
