Congratulations to Holly! Our guest judge was archivist Joan Gearin, who thought your caption did add up. Check your email for your discount code to the eStore.
(We should note that Joan is the author of the most popular Prologue article ever written. Every time The Sound of Music is aired on television, “The Real Story of the Von Trapp Family” gets hundreds of hits.)
Joan is also an archivist for the National Archives in Boston, whose Facebook page explains this mysterious image. “Did you know that during World War II Harvard University contracted with the US government to work on radar countermeasures? This image is of an antenna being tested ca. 1943. The National Archives at Boston holds the records of the Harvard Radio Labs documenting Harvard’s work on radar countermeasures, sonar, and other research on psycho-acoustics, electro-acoustics, and optics. RG 227 Records of the Office of Research and Development.”
There’s no antenna in this week’s photo. Whatever is going on is more…low-tech. Tell us what you think is happening in the comments below!
