Jakob Nielsen papers

General, short description of the collection

A short description:
This collection of Jakob Nielsen papers consists mainly of reprints, which Nielsen has received from other scientists and sorted by authors. In addition to the reprints there is other material from some of the persons, i.e. letters, manuscripts, applications for positions etc. All the material is from the period around 1890-1959 and the reprints are in many different languages. However, the additional material is mainly in Danish or German.

The collection is contained in 79 archival boxes of which the first 25 are standard boxes while the rest are Nielsen's original boxes.

Handed over:
The collection was located in the basement of the mathematical library in the E block of the H. C. Ørsted Institute in the fall of 1996. It is not known when and how it was put here. Photocopies of material from the Staatsarchiv Hamburg was added to box 10 in July 1999.


The copyright for the material written by Nielsen belongs to the descendants of Jakob Nielsen. Usually the copyrights of letters belongs to the letter writer and his/her descendants. The copyright of the photocopies from the Staatsarchiv Hamburg in box 10 has to be checked with the Staatsarchiv Hamburg (364-1 Fakultäten/Fachber. der Universität, Mat-Nat 198), where the originals are located.

This inventory was made by Sigurd Elkjær and Kurt Ramskov, July 1998, and translated into English by Ramskov in October 1998. Updated July 1999.

A short biography of Nielsen

Jakob Nielsen (1890-1959) was born on the peninsula Als (then ruled by the Germans) and he studied in Kiel, where he has good contact with Max Dehn. He submitted his doctoral dissertation in Kiel in 1913. During World War I he was drafted by the Germans. Following studies in Göttingen and Hamburg in 1919 he got a professorship in Breslau in 1920. After the reunion of Southern Jutland with Denmark in 1920 he returned to Denmark, where he became lektor at the Royal Veterinary School in 1921. In 1925 he succeeded C. S. Juel as professor of rational mechanics at the Polytechnics. Nielsen was one of the most significant mathematicians in Denmark then. He worked in topology and group theory. He kept the position at the Polytechnics until 1951, where he succeeded the deceased Harald Bohr as professor at the University. However, Nielsen already retired in 1956. He was involved in international work in the United Nations organization UNESCO after World War II.

A survey of the content

Nielsen himself had sorted his papers in three series and in each series he had more or less sorted the material alphabetical according to authors. Nielsen's original division is almost kept with only minor modifications. Remark that the alphabetical ordering is not complete everywhere. So if you are looking for material from a person the best strategy is to make a search on the person's name. Below is an alphabetical list of persons from whom there is other material than reprints. Remark that:
  1. During the registration of the first series on each folder the names of the persons from whom there is material in the folder have been written on the folder. Nielsen himself had written these names on labels on the back, but they have often disappeared. Furthermore, in brackets are added how many reprints there is from each person (some of them perhaps written jointly with others).
  2. Some of the reprints have more than one author, but the additional authors are not included in this inventory.
  3. In a few cases a reprint is not included under the author, but under the person which is its subject (it is the case for some of the obituaries).
  4. Most of the reprints are mathematical, but there is also reprints in physics, astronomy, engineering science (especially telephone engineering), medicine etc.
  5. In many cases it is written if the reprint is a doctoral dissertation, but it is not always the case.
