Jessen was born on 19 June 1907 in

Julius Pal during his first year.[1] In 1925, Jessen graduated from the gymnasium and enrolled at the University of Copenhagen. During his time at the university he got to know Harald Bohr,[2] then a leading figure in Danish mathematics.[3] In 1928, Bohr established a collaboration with Jessen, which would last until Bohr's death in 1951.[4]

After receiving his master's degree in the spring of 1929, Jessen embarked on a stay abroad. Supported by the

Jessen was a professor of descriptive geometry at the

Hans Christian Ørsted Institute. He was the Secretary of the Interim Executive Committee of the International Mathematical Union (1950–1952), and in September 1951 he officially declared the founding of the Union, with its first domicile in Copenhagen.[7] He was also active in the Danish Mathematical Society
. After his death, the society named an award in his honor (Børge Jessen Diploma Award).
