c. 1930s:
The laboratorium of Professor Bohr
“Niels Bohr (1885–1962) was a Danish physicist who made foundational contributions to understanding atomic structure and quantum mechanics, for which he received the Nobel Prize in Physics in 1922. He fled to Sweden to escape Nazi-persecution and successfully pleaded to the Swedish king to allow refuge to all the 8,000 Danish Jews he fled with.”
