Henry Albert Seymour (28 January 1860 – 3 February 1938) was an English secularist, individualist anarchist, gramophone innovator and survey author, and Baconian.

He published the first English language anarchist periodical in Britain and is credited, in 1913, with introducing the Edison disc into the country.

He was involved in the late 19th century radical community in London and it seems likely that Seymour printed material for many individuals and groups.

He was a founding member of Free Currency Propaganda[5] and produced a pamphlet called The Monomaniacs: A Fable in Finance.

[6] Seymour took over editorship of The Adult: A Journal for the Advancement of freedom in Sexual Relationships, following the arrest of George Bedborough, the previous editor.
