The Nobel Foundation's own primary pages apply "posthumous"/"posthumously" only to deaths that preceded the announcement, never to Vickrey's or Steinman's announcement-adjacent deaths

Across the Nobel Foundation's own primary pages — four per-laureate "Facts" pages plus its general "Nobel Prize facts" reference page — the word "posthumous"/"posthumously" appears in descriptive prose only for the two cases where death preceded the announcement. Dag Hammarskjöld's own Facts page states twice: "Dag Hammarskjöld was awarded the Nobel Peace Prize posthumously," and "He is the only Nobel Peace Prize Laureate to have been awarded the distinction posthumously." Erik Axel Karlfeldt's own Facts page uses the identical construction: "Erik Axel Karlfeldt was awarded the Nobel Prize posthumously." Both died before their prizes were announced — the Foundation's own two named pre-1974 exceptions (see claim-nobel-no-posthumous-rule-broken-twice-before-1974).

William Vickrey's own Facts page, by contrast, frames his death only procedurally: "Vickrey passed away on October 11th, 1996, only three days after the announcement of his Economic Sciences Prize" — no sentence on the page uses "posthumous" anywhere. Ralph Steinman's own Facts page gets the same treatment: "The Nobel Assembly was unaware that Steinman had died of cancer three days earlier when it decided to award him the Nobel Prize." The general facts page's account of Steinman's case likewise avoids the word, framing the Board's decision as "an interpretation of the purpose of the rule," not an invocation of a posthumous exception.

The pattern is one-directional: the Foundation's own prose calls an award "posthumous" when, and only when, death preceded the announcement. For the two cases closest to the 1974 statute's text — Vickrey (died after the announcement) and Steinman (the committee's decision predated news of his death) — the Foundation's own pages never reach for the word. This complicates rather than resolves the tension named in question-does-vickreys-case-count-as-posthumous-in-the-foundations-own-terms: the general facts page's rule-clause ("a prize cannot be awarded posthumously, unless death has occurred after the announcement") grammatically permits calling Vickrey's case posthumous, but the Foundation's own descriptive habit never does so for either Vickrey or Steinman. The codified statute text sidesteps the word entirely. Whether the reservation is deliberate institutional usage or an artifact of how each page happens to be written is not established here; only the pattern itself is.
