Pictured here is men working with telegraph and ciphering equipment at the Telegraph and Cipher Bureau, 1903. To read a history of government data collections from pre-electrical technologies to the present day, see “Messages of a Disloyal Character,” “Black Chambers,” and the History of Bulk Data Collection.
