  A very scarce Didiée localizing compass. Like the earlier and better-known Hirtz compass* , the Didiée compass was used  by surgeons in conjunction with x-rays to localize shrapnel, bullets and other foreign bodies  in order to facilitate their removal. The Didiée had a more narrow focus, specially head and neck.

According to Le Blog 14/18: “Jean-Joseph Didiée (1894-1954) was a radiologist and professor at the Val de Grâce Military School. He would have developed this instrument with E.J. Hirtz, who also created a specific compass to locate metals in the body. It made it possible to go from the two dimensions of the radiological image to the three dimensions of the body.”

The example we are offering is in superb condition and retains its original labeled case. Length of case: 15″ or 37.50 cms.
