In short: Interpretation predates writing, yet it remains a largely undocumented force. From the Nuremberg trials to the front lines of modern conflict, interpreters bridge linguistic divides in real time. Often treated as mere support, these professionals hold the power to prevent war, ensure justice, and maintain global diplomatic cohesion.

Interpretation is the real-time oral translation of spoken or signed language, a practice that existed long before the invention of writing. Despite its antiquity, the history of interpretation is a relatively new field of academic study. For centuries, the dominance of written texts meant that interpreters—who worked in the ephemeral medium of speech—were largely ignored by historians. Their work was frequently dismissed as a mundane support activity, and they often faced poor treatment from the scribes and chroniclers who recorded the events they facilitated.

The transition from consecutive to simultaneous interpretation marks a pivotal shift in modern diplomacy. During the 19th century, European leaders often relied on French as a common language, making professional interpreters less necessary. Following World War I, the decline of French fluency among leaders like Woodrow Wilson and David Lloyd George increased the demand for consecutive interpretation. This method, which requires the interpreter to wait for a speaker to pause before rendering the message, was the standard until the mid-20th century. The Nuremberg trials in 1945 introduced the electronic equipment necessary for simultaneous interpretation, a technology developed in the 1920s and 1930s by Edward Filene and Alan Gordon Finlay with IBM.

In high-stakes environments, the role of the interpreter can be a matter of life and death. In military contexts, such as the War in Afghanistan, the absence of effective interpretation often fueled distrust and insurgency. Conversely, in judicial settings, the right to a competent interpreter is considered a fundamental rule of justice, as misinterpretation can lead to a mistrial. Whether in a sound-proof booth at the United Nations or on a battlefield, the interpreter acts as a vital, if often invisible, intermediary whose accuracy defines the success of international cooperation and legal proceedings.
