A. O. Hemming (Alfred Octavius Hemming, 1868–1930) was an English stained-glass artist active in the late Victorian and Edwardian periods. He trained within the Birmingham milieu and is closely associated with the tradition established by Hardman & Co., for whom he worked early in his career, before establishing himself as an independent designer and maker.

Hemming’s stained glass is characterised by lucid figural drawing, restrained but harmonious colour, and a preference for clear narrative composition. His figures are typically calm and dignified, with careful attention to gesture and expression, and his work often balances pictorial detail with legibility at distance—qualities well suited to parish churches and memorial commissions.

Active at a moment of transition in English stained glass, Hemming’s work reflects continuity with High Victorian Gothic traditions while accommodating the quieter tonalities and simplified forms favoured in the early twentieth century. His windows are found primarily in English parish churches, where they often form part of coherent decorative schemes rather than isolated showpieces.

Although less widely known than the major commercial firms of his day, Hemming represents the substantial cohort of skilled independent practitioners who sustained ecclesiastical stained glass production into the Edwardian period, bridging Victorian revivalism and later twentieth-century developments.
