Joseph Abraham Stargardt (17 June 1822 – 30 April 1885) was a German bookseller and business partner of Paul Julius Reuter.
From April to September 1844 he worked at "Amelangschen Buchhandlung" in Berlin and from October to December 1845 at A. Franck in Paris.
In 1846 Stargardt worked in Halle (Saale) at "J. T. Lippert" and in 1847 he and his affiliate Paul Julius Reuter (1816–99) purchased Johann Carl Klage's book and music store in Berlin.
[1] Stargardt applied for Berlin citizenship in August 1847 but on 8 December 1847 he refused to swear the special form of oath provided for Jews.
In 1849 P. J. Reuter was accused of distributing democratic literature and fled to London, where he founded his Telegraphic Office in 1851.
