William B. Hazen

US Army general (1830–1887) who rose through Civil War combat command — Shiloh, Chickamauga, the March to the Sea — before serving as Chief Signal Officer of the Army from 1880 until his death in office in 1887. Matters to this vault as Adolphus Greely's immediate predecessor in that office: Hazen was himself court-martialed in 1885, not for mishandling the Lady Franklin Bay Expedition disaster but — per a Tier-4 account still awaiting Tier 1–2 confirmation — for publicly criticizing Secretary of War Robert Todd Lincoln's refusal to send further rescue aid (claim-hazen-1885-court-martial-was-for-criticizing-lincoln-not-the-expedition-disaster). His 1887 death put Greely, the expedition's most famous survivor, into the Chief Signal Officer's chair two years before that office's "deteriorating" military performance became President Harrison's own stated reason for moving weather forecasting to civilian control.
