A little about myself:

Steen Clemmensen,

born 1948, retired, presently living in Farum, a suburb 25 km north of Copenhagen, Denmark.

Dr.phil. (humanities, heraldry), cand.scient. (Biochemistry), University of Copenhagen; before retirement I worked in regulatory affairs (environment, occupational health and food safety) as a toxicologist, official, advisor or manager for the Danish National Agency for Environmental Protection and National Agency for Food Safety (Institute of Toxicology), ICI Danmark A/S, Dansk Industri (the confederation of employers in manufacture), and National Environmental Research Institute.

Besides the fields of my former professional life and a liking for the pleasures of nature and urban cultural life, my long-standing interests in the political, social and military aspects of history moved into the field of heraldry and the fairly narrow study of how medieval editors of armorials worked.

Member, former secretary, of Societas Heraldica Scandinavica;

Member of the Heraldry Society;

Member of l'Academie Internationale d'Héraldique;

Fellow, Society of Antiquaries, London.

Received Arvid Berghmans heraldiska pris on its revival in 2012, and the Prix Dr. Walburga von Habsburg Douglas 2012 from the Confederation Internationale de Genealogie et d'Heraldique.

Apart from the papers on this website, some of my other publications are:
