Bohr came to Berlin in June, and was gravely concerned. When he returned to Copenhagen, he began looking for a position for Meitner in Scandinavia. He also asked Hans Kramers to see if anything was available in the Netherlands. Kramers contacted Coster, who in turn notified Adriaan Fokker. Coster and Fokker attempted to secure a position for Meitner at the University of Groningen. They found that the Rockefeller Foundation would not support refugee scientists, and that the International Federation of University Women had been flooded with applications for support from Austria. On 27 June, Meitner received an offer of a one-year position at Manne Siegbahn's new Manne Siegbahn Laboratory [ sv ] in Stockholm, then under construction, which would be devoted to nuclear physics, and she decided to accept it. But on 4 July she learned that academics would no longer be granted permission to travel abroad.
