According to the National Park Service's biographical article, Adolphus Washington Greely led an Arctic research expedition (1881–84) that became stranded for three years near Ellesmere Island after relief ships failed to reach it twice, leaving "only seven men—including Greely—alive" at the rescue. The party numbered 25 at departure, and one of the seven died shortly after rescue, leaving 6 ultimate survivors — details the NPS article omits; both are uncontested across institutional accounts (PBS American Experience, https://www.pbs.org/wgbh/americanexperience/features/greely-bios/; Army Heritage Center Foundation, https://www.armyheritage.org/soldier-stories-information/surrounded-by-ice-the-lady-franklin-bay-expedition/), with the primary record being Greely's own 1886 official report. The disaster drew "criticism of Greely's leadership and rumors of cannibalism" among the survivors. Despite this, Greely was promoted to brigadier general (1886), made Chief of the Signal Corps in 1887, and "served as director of Signal Corps' U.S. Weather Bureau from 1887 until 1891."

The point of interest is the inversion of expected credentials: the man running the national weather service during those years was publicly famous for surviving a polar catastrophe, not for meteorology. Greely had, however, come up through the Signal Corps — studying telegraphy under its founder Albert Myer as a junior officer — which fits the institution's origins as an Army telegraph operation (claim-us-national-weather-service-born-1870-inside-army-signal-service). His tenure ended with the Bureau's transfer to civilian control (claim-1890-91-weather-service-transferred-to-agriculture-at-harrisons-request).

The cannibalism element is a hedged rumor here, and this note does not assert it as fact: the claim rests on a Tier-3 secondary summary rather than on the primary record. Greely's own account, Three Years of Arctic Service (1894), is the unread primary source; verification is routed to question-verify-greely-arctic-expedition-cannibalism-primary. The directorship dates and career facts are uncontested biography and clear the Tier 3–4 floor for that claim type.

Update, 2026-08-07: the cannibalism question above is now substantiated well beyond this note's Tier-3 hedge, on three independent tracks: a contemporaneous 1884 medical-press account citing postmortem evidence (claim-1884-medical-journal-cited-epidermis-in-stomachs-as-cannibalism-proof), a 2002 peer-reviewed bioenergetic reanalysis concluding cannibalism "seems certain" from the documented food shortfall (claim-2002-bioenergetic-study-finds-greely-expedition-food-shortfall-implies-cannibalism), and Greely's own 1886 primary memoir, which conspicuously declines to detail or deny the charge (claim-greely-1886-memoir-declines-to-address-cannibalism-charge). This note's own text still carries only the Tier-3 hedge; the three linked notes carry the fuller record. See also the new hub pages entity-adolphus-greely and entity-lady-franklin-bay-expedition.
