Emanuel Querido (6 August 1871 – 23 July 1943) was a successful Dutch publisher as the founder and owner of N.V. Em.

Querido had close connections with the diamond-polishing trade and supplied the library of the Dutch labour union for diamond workers.

Only a few days after the occupation of Amsterdam, the Querido publishing house was struck by the German secret police Gestapo.

Querido had to leave the publishing business and with his wife retreated to the town of Laren where he had owned a house since 1929.

Fritz Landshoff, a Jew and foe of the Nazis was by chance in London during the German advance to the Netherlands and succeeded in escaping to the United States.
