The history of mathematics
During the period 19911999 I worked in the history of mathematics, first by attending courses and writing my master thesis in the subject, then by doing my Ph.D. project on the Danish mathematician Harald Bohr and finally as a researcher at the University of Copenhagen. This tab presents my working areas and a list of my works is available. The main subjects of my works have been:
 Danish mathematics focusing on Harald Bohr (18871951) and the first third of the 20th century.
 Archival material  how it is found and how to make it accessible on the net.
