Tesla's Seized Papers Released to Sava Kosanović and Shipped to Belgrade

The United States Office of Alien Property releases the Nikola Tesla papers it had seized in January 1943 to Sava Kosanović, Tesla's nephew and the Yugoslav ambassador to the United States. The two truckloads of material taken from the Hotel New Yorker and from the existing Manhattan Storage and Warehouse Co. holdings, plus the abstract filed by Dr. John G. Trump's evaluation team, are shipped to Belgrade. Kosanović becomes the founding figure of what later becomes the Nikola Tesla Museum. According to subsequent Tesla scholarship a sealed box of materials present in Tesla's room on the day of his death is not catalogued in the Belgrade accession; its contents remain unaccounted for in the documentary record.
