Northern Art Investigations (NAI), officially founded after two decades of undercover work handling major cases in different fields by investigative art historian Jan Hendrik Geschke in 2018 and based near the north shore of the Alster lake in central Hamburg, with a field office on Prinsengracht in Amsterdam, specializes in fraud research, authentification and the recovery of artworks mistakenly deemed non-original. In close collaboration with leading lawyers in the field, digital specialists, forensic experts and when and where necessary the authorities, Jan Hendrik and the NAI team have saved major artworks from destruction, fought clueless foundations, assisted in the recovery of art stolen during WWII and discreetly solved a few quite prominent cases.
