Kafka Safety Deposit Boxes Being Opened
Craig Morgan Teicher — July 19th, 2010

Researchers and experts from Israel and Germany believe that some of the boxes may contain manuscripts by Kafka, widely considered one of the greatest writers of the 20th century, or documents that can shed additional light on the mysterious life of the artist.
The scene sounds like it came out of a movie, with suited lawyers barging into a bank where some of the boxes were kept, court order in hand, while Eva Hoffe charged in screaming in an effort to stop the boxes from being opened. Apparently, there is a long and complicated saga leading up to this even, involving Haaretz itself filing a suit to have these papers made public.
At present, all that’s slated to happen is that the lawyers will compile an inventory of what’s in the boxes.
