7 October 2005 is the 120th anniversary of Niels Bohr's birth in 1885, 70th anniversary of the first group photograph in 1935 and 40th anniversary of the renaming of the institute in 1965 to Niels Bohr Institutet. (See NBI history) The Institute Group Photograph The first group photograph of the staff and guests at the Institute was taken in 1935 as a gift for Niels Bohr on his 50th birthday. The tradition has continued since then every year on or near Bohr's birthday, 7 October. There are only a few gaps in the series of photographs - 1943-44, when Bohr had to flee the country during the war; and 1962, the year of Niels Bohr's death.
