Bernard Hartmut Breslauer (1 July 1918 – 14 August 2004) was a German antiquarian book dealer and collector, who lived in turn in Germany, England and the United States.
Bernd was ejected from his secondary school on racist grounds in 1935 and worked as an apprentice to Leo Olschki in Florence and then in his father's bookshop.
Breslauer was interned as an enemy alien on the Isle of Man on the outbreak of war in 1939 and his father died in Bloomsbury the following year during the Blitz.
At the war's end he resumed trading as a bookseller from his mother's house in Chiswick and in 1947 opened a shop in the City of London.
He moved to Fifth Avenue in New York in 1977 and a year later bought a Gutenberg Bible for the unprecedented price of $2.2 million at a Christie's auction for the Württembergische Landesbibliothek in Stuttgart.
