attaché

Attaché is the past participle of the French verb attacher — to attach, to fasten. In diplomatic usage, it described a person attached to an embassy or legation in a subordinate capacity: a junior official affixed, as it were, to a senior mission. The word entered diplomatic French in the early nineteenth century, when the Congress of Vienna's aftermath produced a profusion of formal international missions requiring large staffs.

The attaché occupied a curious social position. He was an insider — privy to the confidential work of the mission — but also an apprentice, often a young man of good family learning the craft of diplomacy from proximity to its practitioners. Military attachés were a specific creation: officers assigned to embassies abroad to observe and report on foreign armies. Their existence was an open secret — a formalized species of sanctioned observation that nations accepted as a feature of the system.

The term attaché case entered English in the late nineteenth century, describing the slim flat briefcase that diplomats carried. The case was named for the person; the person's title migrated to the object. This is a common linguistic inversion: the word for a specialized user becomes the word for the tool most closely associated with that user. The attaché became his case, and the case outlived the specialized meaning of the title in everyday speech.

Military attachés proved consequential figures. They witnessed maneuvers, assessed fortifications, and sent home detailed reports. The German military attaché in London before the First World War filed reports on Royal Navy readiness. American attachés in Beijing watched the Chinese military for decades. The attaché's role formalized the ancient practice of intelligence-gathering into something respectable, even routine — a person who observes, fastened to a foreign capital, and reports what he sees.
