scientists adapt wartime devices for peacetime uses

World War I US Navy camoufleurs
Above This is a wonderfully detailed photograph (digitally colorized) from World War I of members of the US Navy’s Camouflage Section in Washington DC. Headed by Everett Longley Warner, and referred to as the Camouflage Design Subsection, these four men are in process of assembling wooden ship models. When completed, these models were then painted in camouflage patterns, and subsequently tested (in a periscope-equipped observation theatre), to determine their effectiveness in causing German U-boat gunners to make miscalculations in preparing to fire torpedoes.

We were reminded of this photograph when we recently found an article in the New York Sun, dated April 27, 1919, p. 8, as shown below in a restored and rearranged version. It is one of a series of US government photographs that were released to the public for use in news articles, perhaps in 1918 or early 1919. It was reproduced in the top left of what is nearly a full-page article. In the bottom center of the article, I have inserted a much clearer version of the same photograph.

A full-size scan of the original article can be found online, by searching through newspaper archives. The small-scale version posted here is not readable as such, but the topmost headline is: Scientists Hard at Work Turning War Inventions to Peace Uses. It’s a fairly detailed article, and it talks about aspects of camouflage-related research that one rarely sees discussed. During the war, underwater microphones were used by both sides of the conflict as a way of detecting the approach of enemy ships or submarines that were not yet visible. In this article, it is revealed that (now that the war is about to conclude) those same microphones might be used to detect the location and condition of miners who become buried underground when mines collapse.

There is even a brief description of the interior workings of the work area of the Design Subsection, which was located in “the new Navy Building.” The article continues: “At the rear of the office is a door leading into a back room which presents a very unusual appearance. Against the wall appears a collection of miniature ships carefully modeled and painted in curious and bizarre colors. An odd looking instrument is noted which, it later develops, is the periscope of a submarine.”
