Events
Nikola Tesla's papers: the 1943 seizure and FBI file
Documented · occurred Handling What these labels mean →When Tesla died (7 Jan 1943, Hotel New Yorker), the Office of Alien Property seized his papers and effects, despite his US citizenship since 1891, amid wartime concern over his claimed particle-beam 'death ray'. MIT's Dr. John G. Trump (Donald Trump's uncle) reviewed them over several days and reported they were 'primarily of a speculative, philosophical and promotional character' with 'no new sound, workable principles'. The FBI released ~250 pages (2011+) and a further 64-page tranche including a catalog of the seized papers (2018, via MuckRock). Most papers went to Tesla's nephew Sava Kosanović and are now at the Nikola Tesla Museum in Belgrade; theories persist that key papers were withheld.
