The publication of Die Lehre von der Mortalität und Morbilität in 1881 established the international reputation of Harald Ludvig Westergaard, a Danish scholar whose work spanned mathematics, economics, and demography. Throughout his career in Copenhagen, he bridge gaps between abstract statistical theory and real-world observation, documenting the evolution of vital statistics through the end of the nineteenth century.
Academic Formation and Early Work
Born in Copenhagen in 1853, Westergaard attended the Metropolitanskolen and the Technical University of Denmark. During 1877, he traveled to England and Germany for studies. In England, he encountered William Stanley Jevons, who subsequently referenced Westergaard's mathematical contributions in the 1879 edition of Theory of Political Economy. Following this period, Westergaard focused his research on demographic and statistical inquiry rather than purely mathematical economics.

Westergaard gained significant professional experience at the Danish Insurance Office between 1880 and 1882. This work informed his later academic trajectory. Appointed as a lecturer at the University of Copenhagen in 1883, he attained the rank of professor by 1886. He served as the university rector from 1914 to 1915 and continued his faculty responsibilities until his retirement in 1924.
Statistical Theory and Historical Documentation
In his final major publication, Contributions to the History of Statistics released in 1932, Westergaard explored the history of economic and vital statistics. He expressed skepticism toward the prevailing influence of probability calculus, noting that authors often prioritized abstract theories over empirical reality. This perspective defined his approach to the field, favoring grounded analysis over speculative mathematical modeling.
Honours and Legacy
Westergaard received numerous accolades throughout his life. He was awarded an honorary doctorate by the University of Copenhagen in 1902 and the Gold Medal of the Anders Sandøe Ørsted Prize in 1911. His honors included the Decoration of the Cross of Honour of the Dannebrog in 1907, the Medal of Merit in Gold in 1930, and several grades of the Order of the Dannebrog, culminating in the Grand Cross in 1935. He was also a member of the Royal Swedish Academy of Sciences.
