Ansgar Kristensen was born on the island of Falster in Denmark. Before studying at the Royal Academy of Art in Copenhagen, he took lessons at the Cobra Artist Asger Jorn.
He financed his studies among other things by taking roles as supernumerary at the State Theatre in Malmö (Sweden). As a result of these roles he later went on to train as set- designer. Ansgar K. got involved in the theatre as well as Opera in Vienna and Malmö. He received commissions from the business community and private individuals for large format wall paintings.
In the nineteen seventies his theatre and stage work brought him to Düsseldorf in Germany. He has been working here for several years as a freelance artist.
His art works are hanging in different museums and private collections. In 1999 his „Edition 3“ was produced in a limited edition.
