Measuring tools that made history
The Central Intelligence Agency (better known as CIA) released some archive photos of measuring tools used by the Cartography Section of General William Donovan’s Office of Strategic Services (OSS) – a precursor to the CIA during World War II – to mark the its 75th anniversary. The OSS produced about 8,000 hand-drawn maps and 64 plaster topographic 3-D models in support of the war effort. As written in the CIA’s flickr page, “Many of their products played crucial roles in the planning and execution of major military operations in the European, North African, and Asian Theaters”, and these are just a small few of the ones used. Their stunning manufacturing might bring back manual measuring as a must-do brain training.
