Johannes Mollerup

Johannes Mollerup (3 December 1872 to 27 June 1937) was a Danish mathematician. He studied at the University of Copenhagen and received his doctorate there in 1903; the Dansk Biografisk Leksikon records that he took his master's degree in mathematics in 1896 and that his doctoral thesis was a study of the axioms of plane geometry. The same dictionary notes that he became a docent in mathematics at the university in 1915, that his papers are scattered through journals and the proceedings of the Royal Danish Academy of Sciences and Letters, that he contributed to Pascal's Repertorium der höheren Mathematik, and that he wrote a textbook of mathematical analysis together with Harald Bohr. He is remembered chiefly for the Bohr-Mollerup theorem, which he developed with Harald Bohr and which gives an easy characterization of the gamma function.
