What was the original name of the institute founded by Niels Bohr in 1921?

The institute founded by Niels Bohr in Copenhagen was originally called the Institute of Theoretical Physics.

Bohr began campaigning for the institute during the First World War, seeking a permanent home for theoretical physics in Denmark. He gained support from the Danish government, the Carlsberg Foundation, scientists, and private donors. Legislation establishing it was passed in 1918, and the institute opened on 3 March 1921 with Bohr as its director.

Its location in Copenhagen soon made it one of the world’s most important centers for quantum theory. Researchers including Hans Kramers, Oskar Klein, George de Hevesy, Werner Heisenberg, and many other leading physicists visited or worked there during the 1920s and 1930s.

The name “Niels Bohr Institute” was adopted later. On 7 October 1965, the Institute of Theoretical Physics at the University of Copenhagen was officially renamed in Bohr’s honor, three years after his death. “Bohr Laboratory” and “Copenhagen Institute of Physics” are plausible-sounding but incorrect names.
