Admiral Sir John Thomas Duckworth (1747–1817), 1st Bt

Another portrait of Admiral Sir John Thomas Duckworth, this version at The Box in Plymouth reflects the naval officer's local connections to the West Country maritime tradition. Duckworth's most notable action was his squadron's passage through the Dardanelles in 1807. The portrait reflects Beechey's extensive practice among the English gentry and professional classes, executed with the solid, dependable technique that made him widely trusted across all levels of Georgian society.

The naval portrait follows Beechey's established format for military subjects, with careful attention to uniform detail and a composition emphasizing the sitter's command authority.
